Program that count how many white spaces are between words

Question

I want to make a program in C that count how many white spaces are between words. This is the code, but I can't solve the error that occurred.

#include<stdio.h>
#include<string.h>

int main(){
    char str[200];
    int a[200];
    int i, z, c;
    int WordsCount = 0;
    puts("Give String");
    fflush(stdin);
    gets(str);

    for (int i=0; str[i]!= '\0'; i++){
       
        if (str[i] == ' '){
            WordsCount++;
            int count = 0;
            for (z=i; str[z]!=' '; z++ ){
                count++;
            }

            i = z;
            a[WordsCount-1] = count;
        }
    }
    for (int c=0; c<WordsCount; c++){
        printf("%d", a[c]);
    }



}

Answer 1

At least one problem:

str[z]!=' ' is always false

When str[i] == ' ' is true, z=i; str[z]!=' ' z=i; str[z]!=' ' is false.

Check the next character.

    if (str[i] == ' '){
        WordsCount++;
        //int count = 0;
        int count = 1;
        //for (z=i; str[z]!=' '; z++ ){
        for (z=i; str[z+1]!=' ' && str[z+1]!='\0'; z++ ){
            count++;
        }

        i = z;
        a[WordsCount-1] = count;
    }
