Simple if statement in C language

 In simple if statement, there is only one Condition and depending upon the Condition, a particular set of statements will be executed. The syntax of simple if statement is:

if(Test)
{
Block;
}
Test is the condition made using relational or logical operators.

If condition is true, Block  of statements gets executed. otherwise Block will not execute.

Block  is a set of valid C language statements .

#include<stdio.h>
int main()
{
int a=10;
if(a<0)
  printf("number is -ve");
printf("\nBye");
return 0;
}

In the above program, a is 10. 

Condition a<0 is false so only printf(“\nBye”) would be executed.
