I wrote below program to find reverse number but it's not working. what's the problem ?
Code:#include<stdio.h> int main (void) { unsigned int number, reverse; printf("Enter number to reverse \n"); scanf("%d",number); while (number != 0) { reverse = reverse * 10; reverse = reverse + number % 10; number = number / 10; } printf("Reverse number is = %d \n", reverse); return 0; }
Try initialising your variables before using them.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
unsigned int number = 0;Originally Posted by Salem
unsigned int reverse = 0;
If I put these two lines in program still I am not getting output
result
Enter number to reverse
125
error hello.c file stopped working
What about your scanf line?
Do you recall anything about having to use an &

Thank you for point out my mistake. I forgot to put & in program
You should look to using GCC as your compiler. One of the many useful features is warning you about printf and scanf problems such as that.
