Question
In C programming language:
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 a line's last user-specified character. (2 pts)
Example output for triangleChar = % and triangleHeight = 5:
#include <stdio.h>
int main(void) {
char triangleChar = '-';
int triangleHeight = 0;
printf("Enter a character: ");
scanf("%c", &triangleChar);
printf("Enter triangle height: ");
scanf("%d", &triangleHeight);
printf("* ");
printf("* * ");
printf("* * * ");
return 0;
}
Explanation / Answer
#include <stdio.h>
int main(void) {
int i,j;
char triangleChar = '-';
int triangleHeight = 0;
printf("Enter a character: ");
scanf("%c", &triangleChar);
printf("Enter triangle height: ");
scanf("%d", &triangleHeight);
for(i=0;i<triangleHeight;i++){
for(j=0;j<=i;j++){
printf("%c", triangleChar);
}
printf(" ");
}
return 0;
}
Output:
