Here you will get program for strong number in C.
What is Strong Number?
A number in which the sum of factorial of individual digits is equal to the number is called strong number.
For example, 145 is a strong number because 145=(!1)+(!4)+(!5)=1+24+120=145
The below C program will check whether a given number in strong number or not.
Program for Strong Number in C
#include<stdio.h>
int fact(int n){
int i,fac=1;
for(i=1;i<=n;++i){
fac*=i;
}
return fac;
}
int main(){
int n,t,sum,m;
printf("Enter a number:");
scanf("%d",&n);
m=n;
while(m!=0){
t=m%10;
sum+=fact(t);
m=m/10;
}
if(sum==n){
printf("Strong Number");
}
else{
printf("Not Strong Number");
}
return 0;
}
Output
Comment below if you are facing any difficulty to understand above strong number in C program.
thanks
useful for students
in Program for Strong Number in C
sum=0;
is required
can you add python code too
#include
int factorial(int number)
{
int i,fact=1;
for(i=1;i<=number;i++)
{
fact=fact*i;
}
return fact;
}
int main()
{
int number,digit,sum=0,temp;
printf("Enter a number:");
scanf("%d",&number);
temp=number;
while(temp!=0)
{
digit=temp%10;
digit = factorial(digit);
sum=sum+digit;
temp=temp/10;
}
if(sum==number)
{
printf("Strong Number");
}
else
{
printf("Not Strong Number");
}
return 0;
}
thank u
Sir, This program is not working for number = 10 (10 is a strong number), so what is the actual correct program then. Will you please inform me….
