Write a string to a file.
Example
#include <stdio.h>
#include <stdlib.h>/* exit() function */
int main()
{
char sentence[1000];
FILE *fptr;
fptr = fopen("example.txt", "w");
if(fptr == NULL)
{
printf("Error!");
exit(1);
}
printf("Input string:\n");
fgets(sentence, (sizeof sentence / sizeof sentence[0]), stdin);
fprintf(fptr,"%s", sentence);
fclose(fptr);
return 0;
}
The output result is:
