请编程序将“China"译成密码，密码规律是:用原来的字母后面第4个字母代替原来的字母。例如,字母“A”后面第4个字母是“E”,用“E”代替“A”。因此,“China"应译为“Glmre”。请编一程序,用赋初值的方法使cl,c2,c3,c4,c5这5个变量的值分别为’C’,‘h’,‘i’,‘n’,‘a’ ,经过运算,使c1,c2,c3,c4,c5 分别变为’G’,‘l’,‘m’,‘r’,‘e’。分别用putchar函数和printf函数输出这5个字符。

int main(void) { char c1 = 'C', c2 = 'h', c3 = 'i', c4 = 'n', c5 = 'a'; c1 += 4; c2 += 4; c3 += 4; c4 += 4; c5 += 4; putchar(c1); putchar(c2); putchar(c3); putchar(c4); putchar(c5); printf("\n"); printf("%c%c%c%c%c",c1,c2,c3,c4,c5); return 0; }
#include <stdio.h>
int main() { char c1='C', c2='h', c3='i', c4='n', c5='a'; c1 += 4; c2 += 4; c3 += 4; c4 += 4; c5 += 4; putchar(c1); putchar(c2); putchar(c3); putchar(c4); putchar(c5); }
#include<stdio.h>
int main(){
int i;
char c1='C',c2='h',c3='i',c4='n',c5='a';
putchar(c1+4);
putchar(c2+4);
putchar(c3+4);
putchar(c4+4);
putchar(c5+4);
putchar('\r');
pringf("%c%c%c%c%c\r",c1,c2,c3,c4,c5);
return 0;
}
#include<stdio.h> #include<math.h> #include<string.h> int main() { char a[10]={"China"}; for(int i=0;i<strlen(a);i++) { if(a[i]>='A'&&a[i]<='Z') { a[i]='A'+(a[i]-'A'+4)%26; } else if(a[i]>='a'&&a[i]<='z') { a[i]='a'+(a[i]-'a'+4)%26; } } printf("%s\n",a); }

密码转换的关键在于相应字符的ascii加4进行赋值修改原来的字符即可，修改完成后即为相应的密码，在使用putchar和printf进行相应输出即可。
#include<stdio.h> int main() { char c1 = 'C', c2 = 'h', c3 = 'i', c4 = 'n', c5 = 'a'; c1 = c1 + 4; c2 = c2 + 4; c3 = c3 + 4; c4 = c4 + 4; c5 = c5 + 4; //使用putchar输出 printf("使用putchar输出: "); putchar(c1); putchar(c2); putchar(c3); putchar(c4); putchar(c5); printf("\n"); //使用printf输出 printf("使用putchar输出: %c%c%c%c%c\n", c1, c2, c3, c4, c5); return 0; }
The road of your choice, you have to go on !
