Question

Create program that sorts words of a string based on first letter of each word. Use C programming language.

- Only use stdio.h and string.h

- Remove any newline \n from input string

- Use insert function

- Input prompt should say "Enter string of your choice: "

- Output should print sorted string on new line

Example:

    Enter string of your choice: this is a string

    a is string this

Answer 1

Code:

#include<stdio.h>
#include<string.h>
#define MAX 100
int main(){
   int i,j,count=0;
   char input[MAX],str[MAX][MAX],temp[MAX];
   printf("Enter String: ");
   scanf("%[^\n]%*c", input);
   j=0;
   for(i=0;input[i]!='\0';i++) {
       if(input[i]!=' ') {
           str[count][j++] = input[i];
       } else {
           count++;
           j=0;
       }
   }
   for(i=0;i<=count;i++)
      for(j=i+1;j<=count;j++){
         if(strcmp(str[i],str[j])>0){
            strcpy(temp,str[i]);
            strcpy(str[i],str[j]);
            strcpy(str[j],temp);
         }
      }
   printf("Sorted Strings: ");
   for(i=0;i<=count;i++)
      printf("%s ",str[i]);
   
   return 0;
}

Output:
