C Program To Print Strong Numbers From 1 To N
Let us learn how to print strong numbers from 1 to n in C programming language. This code below is to check if a number is a strong integer or not in C programming using functions, while and for loops.
It is important that we should know how a for loop works before getting further with the C program. A strong number makes use of the factorial in C programming.
What is a Strong Number?
A number is said to be a strong number if the sum of the factorials of the digits of a number is equal to the number itself.
145 = (1!) + (4!) + (5!)
40585 = (4!) + (0!) + (5!) + (8!) + (5!)

C Program To Print Strong Numbers from 1 To N
int count, j, temp, limit, sum = 0, fact;
printf("\nStrong Numbers Between 1 To %d\n", limit);
for(count = 1; count <= limit; count++)
temp = count;
while(temp != 0)
fact = 1;
for(j = 1; j <= temp%10; j++)
fact = fact * j;
sum = sum + fact;
temp = temp/10;
if(sum == count)
