程序如下：

#includevoid main()

{

int a,b;

long c;

unsigned long d;

unsigned int e;

char f;

float g;

scanf("%d,%d,%ld,%lu,%u,%c,%f",&a,&b,&c,&d,&e,&f,&g);

printf("int %d,%d,%d,%d,%d,%d,%d",a,b,c,d,e,f,g);

printf("unsigned int %u,%u,%u,%u,%u,%u,%u",a,b,c,d,e,f,g);

printf("long %ld,%ld,%ld,%ld,%ld,%ld,%ld",a,b,c,d,e,f,g);

printf("short %hd,%hd,%hd,%hd,%hd,%hd,%hd",a,b,c,d,e,f,g);

printf("signed char %c,%c,%c,%c,%c,%c,%c",a,b,c,d,e,f,g);

printf("float %f,%f,%f,%f,%f,%f,%f",a,b,c,d,e,f,g);

}
