Question

This program will output a right triangle based on user specified height triangleHeight and symbol triangleChar. It is strongly suggested to use the for loop for this solution.
(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.


(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.


Example output for triangleChar = % and triangleHeight = 5:


Enter a character:

%

Enter triangle height:

5


%

% %

% % %

% % % %

% % % % %


#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");


printf("* \n");

printf("* * \n");

printf("* * * \n");


return 0;

}

Answer 1

The program illustrates the use of loops;

Loops are program statements that are used to perform repetition

The complete program

The modified program in C, is as follows:

#include<stdio.h>

int main(void) {

   char triangleChar; int triangleHeight;

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

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

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

       printf("\n");

       for(int j = 0;j<=i;j++){

           printf("%c",triangleChar);

       }

   }

   return 0;

}
