我的代码有问题，它没有使用带空格的完整字符串

Question

#include <stdio.h>
#include <stdlib.h>

struct fighter
{
    char *name, *category;
    int weight, age;
};

void enter_data(struct fighter *f, int n);
void display(struct fighter *f, int n);

int main(int argc, char const *argv[])
{
    int n;
    struct fighter *f;

    printf("Enter no. of fighter: "); scanf("%d",&n);

    f = (struct fighter *)malloc(n*sizeof(struct fighter));

    enter_data(f, n);
    display(f, n);
    return 0;


    for(int i=0; i<n; i++){
        free((f+i)->name);
        free((f+i)->category);
    }
    free(f);
}

void enter_data(struct fighter *f, int n){
    for(int i=0; i<n; i++){

        (f+i)->name=(char *)malloc(40*sizeof(char));
        (f+i)->category=(char *)malloc(40*sizeof(char));

        fflush(stdin);
        printf("Enter name of fighter: "); 
        scanf("%s[^\n]",(f+i)->name);
        //its not working full name, when I'm trying to give full name with space (ie. John Trump) its not working but when I'm giving only first name (ie. John) its working fine...

        fflush(stdin);
        printf("Enter age of fighter: ");  
        scanf("%d",&((f+i)->age));
        printf("Enter weight of fighter: ");  
        scanf("%d",&(f+i)->weight);
        printf("Enter category of fighter: "); 
        scanf("%s[^\n]",(f+i)->category);
    }
}

void display(struct fighter *f, int n){

    for(int i=0; i<n; i++){
        printf("\n\n");
        printf(" Name of fighter: "); 
        puts((f+i)->name);
        printf(" Age of fighter: ");  
        printf("%d \n",(f+i)->age);
        printf(" Weight of fighter: ");   
        printf("%d \n",(f+i)->weight);
        printf(" Category of fighter: "); 
        puts((f+i)->category);
    }
}

在 enter_data() 函数中查看我已经评论了我的问题...

当我用空格给出全名时，它不会占用其余部分 输入并直接跳到循环的下一次迭代。但是当我在 给出名字或没有空格的名字然后它工作正常。

This imgae is a output sceenshot when I'm giving full name.

This imgae is a output sceenshot when I'm giving first name only or name with no space.

见How do you allow spaces to be entered using scanf?

另外，您的return 0 应该在 循环之后释放资源。
