if condition in c:

 C if condition:

Basic syntax of if conditions:

if(  //condition  ){

work

}

Logic in flow Chart:

How if statement works:

The if conditions statement works ,when our given condition (  ) are true.

When it is false ,then if conditions block will be skipped normally.

Block is the braces { }.

Example:

Question-1: Write a C program .When sum of two number is greater than 10,

print Yes.

Solutions:

here you see we don't use curly braces. Because we needed only single

line of code which will executed

#include<stdio.h>

int main(){

    int a=5,b=6;

    if((a+b)>10)

    printf("Yes");

}

Note: If we don't use {} our code will execute the next one single statement.

And if conditions will not make a block.

Question-2: Write a C program .When sum of two number is greater than 10,

print Yes and print print the sum and minus of to variable.

Solutions:

#include<stdio.h>

int main(){

    int a=5,b=6;

    if((a+b)>10){

    printf("Yes");

    printf("\nsum of tow variable:%d",a+b);

    printf("\nminus of tow variable:%d",a-b);

   

    }

}

In here we used curly braces ,so that our code can execute all line. mainly we create a block

Note: it is not necessary to must use else in ours code:
