We can execute one group of statement if expression is true and another group of statements if expression evaluates to false. This is done by if else structure.
Syntax:
if (condition)
{
statements_1;
}
else
{
statements_2;
}
Example
main()
{
int num;
printf(”enter a number\n”);
scanf(”%d”, &num);
if(num<10)
printf(”\nnumber entered is less than 10″);
else
printf(”\nnumber entered is greater than 10″);
}
Output:
enter a number
12 (say)
number entered is greater than 10
- Nested if else
if(condition)
{
if(condition)
{
block of statements;
}
else
{
block of statements;
}
else
{
block of statements;
}
Example
main()
{
int a=1,b=1;
if(a==0)
if(b==0)
printf(”Hi”);
else
printf(”Bye”);
}
Output:
No output..
