谢谢各位网友帮我尽量早点给我提供答案

Answer 1

void main()
{
int b;
float a,x,y;
char c1,c2;
scanf("%f",&a);
scanf("%d",&b);
scanf("%f",&x);
scanf("%f",&y);
scanf("%s",&c1);
scanf("%s",&c2);
printf("a=%f",a);
printf("b=%d",b);
printf("x=%f",x);
printf("y=%f",y);
printf("c1=%s",c1);
printf("c2=%s",c2);
}

Answer 2

#include "stdio.h"

void main()
{
int a,b;
float x,y;
char c1,c2;
scanf("%d%d%f%f%c%c",&a,&b,&x,&y,&c1,&c2);
}

Answer 3

#include "stdio.h"

main()
{
int a,b;
float x,y;
char c1,c2;

printf("a,b,x,y,c1,c2\n");
scanf("%d,%d,%f,%f,%s,%s",&a,&b,&x,&y,&c1,&c2);
printf("\na=%d,b=%d,x=%f,y=%f,c1=%s,c2=%s\n",a,b,x,y,c1,c2);
}
