Question

This program will output a right triangle based on user specified height triangleHeight and symbol triangleChar. (1) The given program outputs a fixed-height triangle using a * character. Modify the given program to output a right triangle that instead uses the user-specified triangleChar character. (1 pt) (2) Modify the program to use a nested loop to output a right triangle of height triangleHeight. The first line will have one user-specified character, such as % or *. Each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangleHeight. Output a space after each user-specified character, including after the line's last user-specified character. (2 pts) Example output for triangleChar = % and triangleHeight = 5: Enter a character: % Enter triangle height: 5 % % % % % % % % % % % % % % % LAB ACTIVITY 4.15.1: Ch 4 Warm up: Drawing a right triangle (C)

char triangleChar;
int triangleHeight;

printf("Enter a character:\n");
scanf("%c", &triangleChar);

printf("Enter triangle height:\n");
scanf("%d", &triangleHeight);

Answer 1

Answer:

#include <stdio.h>

int main(void) {

   char triangleChar;

   int triangleHeight;

   printf("Enter a character:\n");

   scanf(" %c", &triangleChar);

   printf("Enter triangle height:\n");

   scanf("%d", &triangleHeight);

   printf("\n");

   int i, j;

   for(i = 0; i < triangleHeight; ++i) {

       for(j = 0; j <= i; ++j) {

           printf("%c ", triangleChar);

       }

       printf("\n");

   }

   return 0;

}

Explanation:

• Get the character and height as an input from user.
• Run the outer loop up to the height of triangle.
• Run the inner loop up to the value of i variable and then display the character inside this loop.
