C Exercises: Check whether a number is a Pronic Number or Heteromecic Number or not

C Numbers: Exercise-19 with Solution

Write a program in C to check whether a number is a Pronic Number or Heteromecic Number or not.

Test Data
Input a number: 132

Sample Solution:

C Code:

# include <stdio.h>
# include <stdlib.h>



int main()
{
    int prno,i,n,flg;
	printf("\n\n Check whether a number is a Pronic Number or Heteromecic Number or not: \n");
	printf(" ----------------------------------------------------------------------------\n");
	printf(" Input a number: ");
	scanf("%d",&prno);
    for(i=1;i<=prno;i++)
        {
            if(i*(i+1)==prno) 
            {
            flg=1;
            break;
            }
        }
  
            if(flg==1)
            {
			printf(" The given number is a Pronic Number.\n");
            }
            else
            {
			printf(" The given number is not a Pronic Number.\n");
            }
}

Sample Output: 

 Input a number: 132                                                                                          
 The given number is a Pronic Number.

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
