Program to Check Whether the Person is in Teen Age or Not in C | C Program

Here's a C program to check whether the person is in teen age or not with output and proper explanation. Here we find out whether a person is a teenager or not by using an if-else condition and C logical operators.

# include <stdio.h> 
# include <conio.h> 
void main() 
{ 
 int age ; 
 clrscr() ; 
 printf("Enter the age : ") ; 
 scanf("%d", &age) ; 
 if(age >= 13 && age <= 19) 
  printf("\nThe person is in teen age.") ; 
 else 
  printf("\nThe person is not in teen age.") ; 
 getch() ; 
} 
 

Output of above program is

Enter the age : 18
The person is in teen age.

Explanation of above program

Here first user enters a number specifying an age. Then in the If part of If-else condition we check whether the previously entered age is between the range of 13-19 i.e. the teen age. If the age that user entered is indeed between 13 and 19 then the If block gets executed otherwise the else part will be executed.

Note: In the If condition here, if you notice you'll see that we are using logical AND (&&) operator for the conjunction of two conditions i.e. age >= 13 and age <= 19. That means the if part will only gets executed when both the conditions are true.
