content copy to another file using c

Question

If I write

char ar[100];
strcpy(ar, "I am in child\n");
write(fd, ar, strlen(ar))

It will copy "I am in child" to file located in fd using open function.

But how to write

printf("you got %d points\n",dice);

to another file in C? dice is an integer.

Answer 1

You should use fprintf() .

#include <stdio.h>

int main(void) {
    int dice = 0;
    FILE* fp = fopen("your_file_name.txt", "w");
    if (fp == NULL) {
        perror("fopen");
        return 1;
    }
    fprintf(fp, "you got %d points\n", dice);
    fclose(fp);
    return 0;
}
