if else statement: uppercase to lowercase char/lowercase to uppercase char
Hello Guys!!! How are you? Hope, you all are well by the grace of Almighty. Today we do a c programming code about uppercase-lowercase conversion. Let's look at the problem.
Problem: Input a character. If the character is between "A"-"Z" convert to small letter. If the character is between "a"-"z" convert to capital letter.
Solve:
We know that, the ASCII value of "a" is 97 and "z" is 122. In the first condition, this is applied. We also know that, the ASCII value of "A" is 65 and "Z" is 90. In the second condition this is applied.
We can also do this program by the following way:
The difference between any ASCII value of lowercase and uppercase character is 32. In this program, this is used. In line 12 and 17 "x-=32" & "x+=32" means "x=x-32" & "x = x + 32".
We can also do this program by the following way:
In this program, "ctype.h" header file is used. toupper and tolower are library functions. toupper function converts any character into uppercase character & tolower converts any character into lowercase character.

If Else Statement (Conditional): Beginning
Hello Guys!! How are you, all? Hope you all are well by the grace of Almighty ALLAH. Today we learn about the conditional Statement.
Conditional Code:
- The if statement.
- The if.....else statement.
- The if.....else if.....else statement.
Conditions:
- Using relational or conditional operators.
- Using logical operators.
Relational or conditional operators:
- == means 'is equal to'
- != means 'is not equal to'
- < means 'is less than'
- > means 'is greater than'
- <= means 'is less than or equal to'
- >= means 'is greater than or equal to'
Logical Operators:
- && means 'AND'
- || means 'OR'
- ! means 'NOT'
Note: Result of the condition is always wither true(1) or false(0)
Example:
1>2 Ans. 0
1<2 Ans. 1
1==2 Ans. 0
If the value of the condition is any positive or negative number except 0 or 1, it always consider that number as a true value.
The If Statement
if (condition)
{
statement;
}
Multiple statement within If
if (condition)
{
statement 1;
statement 2;
-----------;
statement n;
}
The if else statement
if (condition)
{
statement 1;
statement 2;
}
else
{
statement 1;
statement 2;
}
The if-else if-else statement
if (condition)

Expression Evaluation: Electrical Force
Hello Friends!!! hope, you all are well by the grace of Almighty. Today we learn how to find out the electrical force. Let's look at the problem.
Problem: Calculate the electrical force F between charges q1 and q2 separated by a distance r meters using Coulombs Law as given below. Charge quantities q1 and q2 are input data in this problem and force F is the output quantity. The value of Epsilon naught is 8.85E-12 F/m is a constant quantity and ignore units.
F = (q1 x q2)/ (4 x pi x epsilon naught x r x r).
Solve:
In this program #define is used. We define the value of pi after the header file. #define is used by following way:
#define constant_name constant_value
"E" is used for "10^". If we want to see result in "E" format, we have to use "%E". In this program it is used.

Expression Evaluation: Separate Digits from a Four digits integer number
hello guys!!! Hope, you all are well by the grace of Almighty ALLAH. Today we learn how to separate digits from a four digit integer number.
We can try the following process of separating digits from a integer number:
If the number is 1234, then when we divide it with 10, we will find "4" as the remainder. Then again we divide the number with 10. Then, we will find 123 as quotient. After this, again we divide 123 by 10 and find "3" as the remainder. Then, if we divide 123 with 10, we will find 12 as quotient. After this, when we divide 12 by 10 we will find "2" as remainder. Then when we again divide 12 by 10, we will find "1" as quotient.
Now, "1", "2", "3" & "4" are the separated digits.
Now, we can write C programming code by using this formula. Let's look at the program:

Expression Evaluation: Division
Hello guys!!! Hope, you all are well by the grace of Almighty. Today we learn, how to divide in C programming. Let's look at a program:
Output: Division: 10 / 3 = 3
This program is wrong because all of us know that 10 / 3 = 3.33. 3.33 is a float number. so, we can try this code by letting "s" as a float variable. let's look:
Output: Division: 10/3 = 3.000000
This program is wrong too because the result is wrong. so, we can try this code by letting all variables "a", "b" & "s" as a float variable. Let's look:
Output: Division: 10.000000 / 3.000000 = 3.333333
Now, this program is correct. But it is looking odd. If we want our output as 10 / 3 = 3.33, then we have to write this program in this way:
Output: Division: 10 / 3 = 3.33
Now this program is perfect. In this program in line no. 8, i write "s=(float)a/b". This is called "Type Casting". We cast "a" to float from int variable. Why we cast ?? Because when divide two numbers, it's result and any of one must be in a float variable. If two numbers are integer then we have to cast any of these numbers. We can also write this code by following way:
Output: Division: 10 / 3 = 3.33
We can also Make an integer number to float number by adding ".0" with it.
Thank you all..:)
Output: Division: 10 / 3 = 3

Expression Evaluation : Addition
Hello guys!!! How are you ?? Think all of you are well by the grace of Almighty. Today we will learn how to add a number with another number in C. Let's look at a program :
Output: Summation: 15
First of all we write a header file #include<stdio.h>. Then write main function. In main function, from "int a" to "int sum" part is called declaration. Then from "a=5" to "sum=a+b" part is called initialization. Then we print the result. In this program, first of all we take three integer type variables called "a", "b" and "sum". Then we initialize 5 into "a" and 10 into "b". In the variable "sum" we initialize "a+b". Finally we print the value of "sum". Here "\n" is used for new line.
We can initialize all same type variable & declare variable and initialize at the same time. we can also print the value of "a+b" without it's value in another variable. If we do it, then this code is look like following:
Output: Summation: 15
If we want to scan the two integer numbers then the code is looked like the following:

If we want to scan the two integer numbers then the code is looked like the following:
Output will depend on input. If inputs are 5 & 10, output will :
Enter Two Numbers: 5 10
Summation: 15
In scanf we scan the address of two variables "a" & "b". In printf generally we print the value of variable.
If we want output more clear, then we can code the following way:
If inputs are "5" & "10", the output will be:
Enter Two Numbers: 5 10
Summation: 5 + 10 = 15
Thank you all...:)
