Answer 1

Here is the code for you:

#include <stdio.h>
#include <stdlib.h>
int readValueInRange(int min, int max)
{
char string[10];
int num;
scanf("%s", string);
num = atoi(string);
while(num < 1 || num > 79)
{
printf("I'm sorry, that number is unrecognized or out of range, try [%i-%i]: ", min, max);
scanf("%s", string);
num = atoi(string);
}
return num;
}
void draw_box(int rows, int cols)
{
for(int i = 0; i < rows; i++)
{
for(int j = 0; j < cols; j++)
printf("%%");
printf("\n");
}
}

int main()
{
printf("Please enter the number of percents you want in your line: ");
int cols = readValueInRange(1, 79);
printf("Please enter the number of lines you want in your box: ");
int rows = readValueInRange(1, 23);
draw_box(rows, cols);
}
