Question

Write a function definition for a function named getValidAge that returns an integer to the calling program. The number returned by the function is a valid age (between 0 and 130 inclusive). Inside the function definition, the user is asked to enter their age, the age is validated using a loop, and the valid age is returned.

Answer 1

//C program


#include <stdio.h>
//function to validate age
int getValidAge()
{
  int age;
  //while loop runs until user enters the age between 0 to 130 inclusive
  while(1)
  {
    printf("\n\nEnter your age:\n");//user input for age
    scanf("%d",&age);
    //condition to check the age in between 0 to 130 inclusive otherwise invalid age
    if(age>=0 && age<=130)
    {
      return age;
      break;
    }
    else
    {
      printf("Entered invalid age");
      continue;
    }
  }
}
int main(void) 
{
  int result;
  result = getValidAge();//function call
  printf("Entered age is : %d ",result); //prints the result
  return 0;
}
