Question

In Programming language C

- How would I convert my words char array into a string array so I can use the strcmp() function and alphabetically sort the words?

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#include <ctype.h>

int main(int argc, char*argv[]){

int i =0;

int j =0;

int count =0;

int length = strlen(argv[1]);

for(i =0; i < length; i++){

if(isalpha(argv[1][i]) == 0 ||isdigit(argv[1][i] != 0)){

count ++;

}

printf("%c",argv[1][i]);

}

char *strings;

int wordNum =0;

int charNum =0;

strings =malloc(length*sizeof(char*));

char words[count][length];

for(i = 0; i < length; i++){

strings[i] = argv[1][i];

}

for(i = 0; i < length; i++){

if(isalpha(strings[i])!=0){

words[wordNum][charNum] = strings[i];

charNum++;

}

else{

words[wordNum][charNum] = '\0';

wordNum++;

charNum =0;

}

}

   printf("\n\n");

for(i = 0; i < wordNum; i++)

{

for(j = 0; words[i][j] != '\0'; j++)

{

printf("%c",words[i][j]);

}

printf("\n\n");

}

printf("\n%d",count);

}

strings =(char *)malloc(length*sizeof(char*));//modified//you have to use (char *) inoder to conver void* to char *

//i don't understand what you are trying to do here,
//but you can strcmp to compare char* words
//if you want any further code, pls comment
//if will provide

//i'm giving you the sample for strcmp
