［C语言］编程：输入一个字符，根据该字符的ASCII码值来判断并输出该字符的类型？

main(void) {

char a=getchar()

if(a>=97 &&a<=122){

printf("字符%d是小写字母",a)

}else if(a>=65 &&a<=90){

printf("字符%c是大写字母",a)

}else if(a>=48 &&a<=57){

printf("字符%c是数字",a)

}else{

printf("字符%c是其他字符",a)

}

}

void main()

{

char ch

printf("请输入一个字符\n")

scanf("%c",&ch)

if(ch>='A'&&ch<='Z')

{

printf("capital letters\n")

}

else if(ch>='a'&&ch<='z')

{

printf("small letters\n")

}

else if(ch>='0'&&ch<='9')

{

printf("figures\n")

}

else

{

printf("others\n")

}

}
