if control statement - Basic Programming Concepts With psudo Code

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.
