Inside the loop, the reversed number is computed using: reverse = reverse * 10 + remainder; Let us see how the while loop works when n = 2345. nn != 0remainderreverse 2345 true 5 0 * 10 + 5 = 5 234 true 4 5 * 10 + 4 = 54 23 true 3 54 * 10 + 3 = 543 2 true 2 54...

Write a Reverse Digits of Number in C to reverse the digits of a given integer. User needs to provide the number initially to the program,then program will reverse the digits of number. Reverse Digits of Number in C Program will divide the number by 10 continuously to get the digits as ...
printf("Enter number of array elements: "); scanf("%d", &nelem); printf("Enter array elements:\n"); for(i = 0; i < nelem; i++) scanf("%d", &num[i]); /* print array elements in reverse order */ printf("Array elements in reverse order:\n"); ...
In the above program, we created two functions countBits() and main(). The countBits() function is used to count the number of bits that need to be flipped to convert a number to another number.In the main() function, we read two integer numbers from the user and calle...
if(reverse==n) printf("%d is a palindrome.",n); else printf("%d is not a palindrome.",n); return 0; } 结果输出: Enter an integer: 12321 12321 is a palindrome. 3、质数检查 注:1既不是质数也不是合数。 源代码: /* C program to check whether a number is prime or not. */ ...
1. Reverse Digits Variants Write a C program to reverse the digits of a given integer. Example: Input: i = 123 i = 208478933 i = -73634 Output: Reverse integer: 321 Reverse integer: 339874802 Reverse integer: -43637 Click me to see the solution ...
