Question

我有一些关于指针的基本问题，我有一个char数组，我正在使用函数提取一些单词我的char数组，我想返回值并打印它主要我有代码但它不起作用，谢谢你帮助

 #include <stdio.h>
#include <stdlib.h>
#include <string.h>
    char cumle[30];
char kelimecikart(char *cumle,char *sozcuk);
int main(){
    int i;
    char sozcuk[30];
    printf("sentence:\n");
    gets(cumle);
    puts(cumle);

    printf("What is the word you want to extract of:\n");
    gets(sozcuk);
    puts(sozcuk);
    printf("\n");

    cumle[0]=kelimecikart(cumle,sozcuk);
    for(i=0;i<17;i++){

        printf("%c",cumle[i]);
    }
}
char kelimecikart(char *dizi,char *cikansoz)
{    
    int a = strlen(dizi);
    int b = strlen(cikansoz);

    int i,j,tmp=0;
    for(i=0;i<a;i++){
        for(j=0;j<b;j++){
            if(*(dizi+i+j)==*(cikansoz+j)){
                tmp++;
            }
            else{
                break;
            }
            }
            if(tmp==b){
                i+=tmp-1;
            }
            else{
                *(cumle+i)=*(dizi+i);
            }
            tmp=0;  
    }   

    return *cumle;
}

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
    char cumle[30];
void kelimecikart(char *cumle,char *sozcuk);
int main(){
    int i;
    char sozcuk[30];
    printf("sentence:\n");
    gets(cumle);
    puts(cumle);

    printf("What is the word you want to extract of:\n");
    gets(sozcuk);
    puts(sozcuk);
    printf("\n");

    kelimecikart(cumle,sozcuk);
    for(i=0;i<17;i++){

        printf("%c",cumle[i]);
    }
}
void kelimecikart(char *dizi,char *cikansoz)
{    
    int a = strlen(dizi);
    int b = strlen(cikansoz);
    int i,j=1;
    for(i=0;i<a;){
        if(j==0){
            i++;
        }
        else if(j==b){
            break;
        } 
        for(j=0;j<b;j++){
            if(dizi[i]==cikansoz[j]){
                i++;

            }
            else{
                break;
            }

        }
    }



    for(;i<a;i++){
        dizi[i-b]=dizi[i];

    }

    return ;
}
