使用scanf()输入数字和文本数据。

#include <stdio.h>

int main( void ){
    char lname[257], fname[257];
    int count, id_num;

    puts("Enter last name, first name, ID number separated /n");
    puts("by spaces, then press Enter./n");

    /* Input the three data items. */

    count = scanf("%s%s%d", lname, fname, &id_num);

    printf("%d items entered: %s %s %d /n", count, fname, lname, id_num);

    return 0;
}
