I'm having trouble rewriting my code.

This is my program:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
char pole[100];
int i = 0;
char *token;
char *space = " \r\n";
while(fgets(pole, 100, stdin)){
    int j = 0;
    token = strtok(pole, space);
    while (token != NULL){
        if (strlen(token) > 0){
            j  ;
        }
        token = strtok(NULL, space);
    } 
    if (strcmp(pole, "x") == 0 || strcmp(pole , "x\n") == 0){
       break;
    }
    i  = j; 
}
for (int x = 0; x < i; x  ){
    printf("Word %d: \n", x);
}
return 0;
}

Input:

Hello I am human
Programming
Apple moon
x

Output:

Word 0: 
Word 1: 
Word 2: 
Word 3: 
Word 4: 
Word 5: 
Word 6:

But I want to write the number of strings at the beginning then the strings like this (without "x"):

3
Hello I am human
Programming
Apple moon

and get this

Word 0: 
Word 1: 
Word 2: 
Word 3: 
Word 4: 
Word 5: 
Word 6:

I've tried this to solve this problem, but it doesn't work

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
char pole[100];
int i = 0;
int cislo;
int cislo2 = 0;
char *token;
char *space = " \r\n";
scanf("%d", &cislo);
while (cislo2 < cislo){
    while(fgets(pole, 100, stdin)){
        int j = 0;
        token = strtok(pole, space);
        while (token != NULL){
            if (strlen(token) > 0){
                j  ;
            }
            token = strtok(NULL, space);
        } 
        }
        i  = j;
        break; 
}
for (int x = 0; x < i; x  ){
    printf("Word %d: \n", x);
}
return 0;
}

I have no idea how to improve my program to get what I want. Please help me.

CodePudding user response：

There are a few things:

1. You need to usewhile (cislo2 <= cislo) otherwise you'll be off by one.
2. Place i = j inside the inner while loop.
3. Why use a while loop if you break out anyway (replace the second while loop with an if)
4. Count up cislo2, otherwise you got yourself an infinite loop

Here is the full code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
    char pole[100];
    int i = 0;
    int cislo;
    int cislo2 = 0;
    char *token;
    char *space = " \r\n";
    scanf("%d", &cislo);
    while (cislo2 <= cislo){
        if (fgets(pole, 100, stdin)){
            int j = 0;
            token = strtok(pole, space);
            while (token != NULL){
                if (strlen(token) > 0){
                    j  ;
                }
                token = strtok(NULL, space);
            } 
            i  = j;
        }
        cislo2  ;
    }
    for (int x = 0; x < i; x  ){
        printf("Word %d: \n", x);
    }
    return 0;
}
