我正在努力解决这个问题.基本上,这个function void check(char *tel, char *c)数组的第一个值必须是数字2,而其他数字必须是数字之间的数字0 and 9.如果满足条件,将打印V,否则将打印F.
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<ctype.h>
void check(char *tel, char *c){
int i;
if(*tel!=2) printf("Error\n");
*c='F';
return; //I guess this return is wrong
if(*tel==2)
for(i=0;tel[i]<9;i++){
if(isdigit(tel[i]));
else{
printf("Error!\n");
*c='F';
break;
return;} //this one might be in bad use too
}
else
*c='V'; //having troubles here.. i'm not seeing a way to fix this
}
int main(){
char number[9]={2,3,4,5,6,7,4,5,3};
char car;
check(number,&car);
printf("%c \n", car); …
