不懂下面编程的意思??新手求问
1:#include <stdio.h>
main()
{
int a,b;
float x,y,z;
char c1,c2;
scanf("%5d%5d%c%c%f%f%*f,%f",&a,&b,&c1,&c2,&x,&y,&z);
printf("a=%d,b=%d,c1=%c,c2=%c,x=%f,y=%f,z=%f",a,b,c1,c2,x,y,z);
}
2:
#include <stdio.h>
main()
{
int a,b;
float x,y;
char c1,c2;
scanf("a=%d,b=%d",&a,&b);
scanf("x=%f,y=%f",&x,&y);
scanf("c1=%c,c2=%c",&c1,&c2);
printf("a=%d,b=%d,x=%f,y=%f,c1=%c,c2=%c\n",a,b,x,y,c1,c2);
}
