Trying to capture output, yes I am new to coding and this is part of an intro course.

#include <stdio.h>

#define MIN 1
#define MAX 30

FILE *fp;

int main(void) {
int i;

fp = fopen_s("csis.txt");

printf("%10s %10s %10s %10s %10s\n", "Value", "Square", "Cube", "4th", "5th");
fprintf(fp, "%10s %10s %10s %10s %10s\n", "Value", "Square", "Cube", "4th", "5th");

printf("%10s %10s %10s %10s %10s\n", "-----", "------", "----", "---", "---");
fprintf(fp, "%10s %10s %10s %10s %10s\n", "-----", "------", "----", "---", "---");

for (i = MIN; i <= MAX; ++i) {
printf("%10d %10d %10d %10d %10d\n", i, i * i, i * i * i, i * i * i * i, i * i * i * i * i);
fprintf(fp,"%10d %10d %10d %10d %10d\n", i, i * i, i * i * i, i * i * i * i, i * i * i * i * i);


}

fclose(fp);
return 0;
}

fopen_s requires more paramaters. You're passing in one param ("csis.txt") and you should be passing 3. See https://msdn.microsoft.com/en-us/library/z5hh6ee9.aspx

fopen_s(&fp, "csis.txt", "rw");

I figured it out.

Just turned off the properties that gave warning to open f_open in safe

nvm
