Question

Playing with strings Assignment

Outcomes:

• Demonstrate the ability to create strings.
• Demonstrate the ability to manipulate strings.
• Demonstrate the ability to write well written code.

Program Specifications:

DESIGN and IMPLEMENT a short program that will:

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

Hint: Use a technique to read in strings that allows spaces:

#include <stdio.h>
int main()
{
   char z[100];
   int n=1;
   do{
       printf("Enter a string\n");
       gets(z);
       printf("\nThe string in forward: ");
       int size=0;
       while(z[size]!='\0')
       {
           printf("%c",z[size]);
           size++;
       }
       printf("\nThe string in backward: ");
       for(int i=size-1;i>=0;i--)
           printf("%c",z[i]);
      
       printf("\nThe string verticaly is\n");
       for(int i=0;i<size;i++)
           printf("%c\n",z[i]);
       int k=0;

               no++;
       }
       printf("\nThe numbers of letter in the string is : %d\n",no);
       printf("Enter 1 to enter one more string else 0");
       scanf("%d",&n);
   }while(n==1);
return 0;
