Program to reverse a string--segmentation fault!
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int
main(void)
{
char* original = (char*) malloc(80 * sizeof(char));
char reverse[80];
char temp[80]; //same as char* temp
char *ptr;
printf("Input: ");
fgets(original, 80, stdin);
ptr = strtok(original, " ");
while(strtok(original, " \n") != NULL) //until end of line
{
ptr = strtok(NULL, " \n");
sprintf("%s", ptr, reverse); //THIS CAUSES THE ERROR
strcpy(reverse, temp);
}//while
printf("%s", reverse);
free(original);
return 0;
}//int main(void)
I am trying to write this program to reverse a string. If I were to give it the string "birds and bees," it would give me bees and birds in response. This program does not work, though, and results in a segmentation fault. What is my error and how do I fix it?
Thank you.
