// Using scanf()/scanf_s()/wscanf() and sprintf()/sprintf_s()/swprintf()

#include <stdio.h>

int main(void)

{

char s[80];

int x;

float y;

printf("Using sprint()/sprintf_s()\n");

printf("---------------------------\n");

printf("Enter an integer and a float, separated by space: \n");

// scanf("%d%f", &x, &y); - using a secure version

scanf_s("%d%f", &x, &y);

// sprintf(s, "Integer:%6d\nFloat:%8.2f", x, y); using a secure version

sprintf_s(s, 80, "Integer:%6d\nFloat:%8.2f", x, y);

printf("\n%s\n%s\n", "The formatted output stored in array s is: ", s);

return 0;

}

Output example:

Using sprint()/sprintf_s()

---------------------------

Enter an integer and a float, separated by space:

210 20.15

The formatted output stored in array s is:

Integer: 210

Float: 20.15
