fprintf（）函数的用法结合代码

#include "stdio.h"
#include "stdlib.h"
typedef struct work{
    char name[20];
    float wage;
}work;                  //typedef 名字重定义  将结构体名字struct work重定义为work 
int main(){
    FILE *fp;
    char filename[20];
    work w;
    int i;
    printf("Please inputs filename:\n");
    gets(filename);
    if((fp=fopen(filename,"w"))==NULL)
    {
        printf("False open file\n");
        exit(0);
    }
    printf("Please input the information of 5 employees:\n");
    for(i=0;i<5;i++){
        scanf("%s%f",w.name,&w.wage); 
        fprintf(fp,"%-10s-%8.2f\n",w.name,w.wage);
    }
    printf("Employee information saved successfully in %s file \n",filename);
    fclose(fp);
    return 0;
}
