C Exercises: Find the Armstrong number for a given range of number

C For Loop: Exercise-30 with Solution

Write a C program to find the Armstrong number for a given range of number.

Sample Solution:

C Code:

/*When the sum of the cube of the individual digits of a number  
 is equal to that number, the number is called Armstrong number. For example 153.  
Sum of its divisor is 13 + 53;+ 33; = 1+125+27 = 153*/
#include <stdio.h>

void main(){
    int num,r,sum,temp;
    int stno,enno;

    printf("Input starting number of range: ");

    printf("Input ending number of range : ");

    printf("Armstrong numbers in given range are: ");
         sum = 0;

             r=temp % 10;
             printf("%d ",num);

Sample Output:

Input starting number of range: 1                                                                             
Input ending number of range : 1000                                                                           
Armstrong numbers in given range are: 1 153 370 371 407

C Programming: Tips of the Day

C Programming - What is the difference between char s[] and char *s?

The difference here is that

char *s = "Hello world";

will place "Hello world" in the read-only parts of the memory, and making s a pointer to that makes any writing operation on this memory illegal.

While doing:

char s[] = "Hello world";

puts the literal string in read-only memory and copies the string to newly allocated memory on the stack. Thus making legal.

s[0] = 'J';
