C Exercises: Find narcissistic decimal numbers within a specific range
C Numbers: Exercise-34 with Solution
Write a program in C to find narcissistic decimal numbers within a specific range.
Test DataInput the lower limit: 100
Input a upper limit: 1000
Sample Solution:
C Code:
# include <stdio.h>
# include <stdlib.h>
# include <stdbool.h>
# include <math.h>
int main()
{
int nl,nu;
printf("\n\n Find the narcissistic decimal numbers between a specific range: \n");
printf(" --------------------------------------------------------------------\n");
printf(" Input the lower limit: ");
scanf("%d",&nl);
printf(" Input a upper limit: ");
scanf("%d",&nu);
printf(" The narcissistic decimal numbers between %d and %d are: \n",nl,nu);
int i,ctr,j,orn,n,m,sum;
for(orn=nl;orn<=nu;orn++)
{
ctr=0;
sum=0;
n=orn;
while(n>0)
{
n=n/10;
ctr++;
}
n=orn;
while(n>0)
{
m=n % 10;
sum=sum+pow(m,ctr);
n=n/10;
}
if(sum==orn)
{
printf(" %d ",orn);
}
}
printf("\n");
}
Sample Output:
Input the lower limit: 100 Input a upper limit: 1000 The narcissistic decimal numbers between 100 and 1000 are: 153 370 371 407

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().
