新装一个小程序输上字显示其他字符

#include <stdio.h>

int main()

{

char ch1, ch2

printf("Please enter two characters: ")

scanf("%c %c", &ch1, &ch2)

printf("The characters you entered are %c and %c.\n", ch1, ch2)

printf("或梁Now I will show you other characters:\n")

printf("A B C D E F G H I J K L M N O P Q R S T U V W X Y Z\n")

printf("a b c d e f g h i j k l m n o p q r s t u v w x y z\n"衫念运)

printf("0 1 2 3 4 5 6 7 8 9 ! @ # $ % ^ &* ( ) - + =\n"高冲)

return 0

}

#include <stdio.h>

#include <math.h>

int main(int argc, char*argv[])

printf("输入一个四耐答位数:")

int input

scanf("%4d",&input)

// 求出输入数字稿亩碧十进制位数
