Answer 1

/*
The following prints a triangle filled with spaces and surrounded by asterisk(*).

If you want to get the user to specify the triangle's size, add something like this to main just after the size declaration:

printf("How large do you want the triangle?\n");
scanf("%d", &size);
*/

#include <stdio.h>

void printChars(char c, int numRepeats) {
for (int i = 0; i < numRepeats; i++) {
printf("%c", c);
}
}

void printSpaces(int numRepeats) {
printChars(' ', numRepeats);
}

int main() {

int size = 12;

printSpaces(size);
printf("*\n");
for (int i = 1; i < size; i++) {
printSpaces(size - i);
printf("*");
printSpaces(i * 2 - 1);
printf("*\n");
}
printChars('*', 1 + size * 2);

return 0;
}
