if( ) is a control statement. it based on some condition. if the condition can true the block of statements can execute other wise skip the statements. syntax if([condition]) { //statement; } example1, #include<stdio.h> #include<conio.h> main() int num=1; { if(num==1) { printf("\n its true"); } } from the above program we can declare the variable named as num and assign the value as 1. then, check the value 1 equal value of num through if statement.the statement can true.so, the block of statements can executed. example2, #include<stdio.h> #include<conio.h> main() int num=5; { if(num==1) { printf("\n its true"); } } suppose the value of num is 5.the block of if statement can skip to execution.
