#include "stdio.h"void main(){char c;printf("please input a character:");c=getchar(); if(c < 32){printf("This is a control character\n");}else if("c >= '0' && c<='9'"){printf("This is an integer\n");}else if ("c>='a' && c<= 'z'"){printf("This is a small letter\n");}else if ("c>='A' && c<='Z'"){printf("This is a capital letter\n");}else{printf("This is another character\n");}}這個(gè)程序我本來是想隨便輸一個(gè)符號就能幫我自動(dòng)歸類但是不管輸入什么都說這是一個(gè)整數(shù)怎么回事?

小唯快跑啊

TA貢獻(xiàn)1863條經(jīng)驗(yàn) 獲得超2個(gè)贊

#include "stdio.h"

void main()

{
char c;
printf("please input a character:");
c=getchar();
if(c < 32)
{
printf("This is a control character\n");
}
else if((c >= '0') && (c<='9'))
{
printf("This is an integer\n");
}
else if ((c>='a') && (c<= 'z'))
{
printf("This is a small letter\n");
}
else if ((c>='A') && (c<='Z'))
{
printf("This is a capital letter\n");
}
else
{
printf("This is another character\n");
}
}
