Hi guys,

I need help with my code. My xcode tells me "Build Failed" and I dont know what I'm doing wrong. I just need a second pair of eyes to look over this. This is for c programming.

Here the assignment:

You are to DESIGN and WRITE a short program that will:

• Allow the user to enter a string with up to 100 letters.
• The program will display the string:
  • Forward
  • Backward
  • Vertical
  • As a triangle made from the letters of the string
• The program will display the number of letters in the string.
• Once everything above was displayed, the program will ask the user if he or she wishes to enter a different string or quit.

YOU CANNOT

• Use global variables, in this or any program ever.
• Use goto statement(s) , in this or any program ever.

Here my Code:

#include

#include

int main(){

int num = 1;

char str[100];

int r,j,k;

while (num==1){

printf("enter word");

scanf("%s", &str);

print("forword ");

printf("%s", str);

printf("backward");

for (r = 0; str[r]!='\0'; ++r){

for (j = r -1; j >=0; r--) {

printf("%c", str[j]);

}

}

printf("vertical");

for (j = 0; str[j]!='\0'; j++) {

printf("%c ", str[j]);

}

printf("triangle");

for (j=1; j <= r; j++) {

for (int k =0; k < j; k++) {

printf("%c", str[k]);

}

printf(" ");

}

printf("NO. of letter in the string: %d", r);

printf("leave?: ");

scanf("%d",&num);

}

return 0;

}
