UC知道C语言·编程 出问题了

#include <stdio.h>
#define Dog 100f
void main()
{
float cats = 10.0f;
float apples = 20.0f;
float pairs = 0.0f;
float milk = 0.0f;
float pea = 0.0f;
pairs= Dog - (cats + apples);
printf("pairs We have %f.",pairs);
printf("The milk is:");
scanf("%f",&milk);
pea = milk + Dog;
printf("OK!we can know %f is milk %f is pea!",milk,pea.);
}
谢谢·
错误应该很多·我对英文不太懂·希望大虾能帮帮忙！

float pairs = 0.0f;

float pea = 0.0f;

printf("pairs We have %f.",pairs);
printf("The milk is:");
scanf("%f",&milk);
pea = milk + Dog;
printf("OK!we can know %f is milk %f is pea!",milk,pea.);
}

由于整型常量只能以字母“u”、“U”、“l”和“L” 为后缀，而 #define Dog 100f 这句中，100是一个整型常量，故不能加上f，可以把这句改成 #define Dog 100.f或 #define Dog 100.0f
还有，main 中最后一句 pea 后面多打了一个点～
这样就行了:
#include <stdio.h>
#define Dog 100 /*去掉f*/
void main()
{
float cats = 10.0f;
float apples = 20.0f;
float pairs = 0.0f;
float milk = 0.0f;
float pea = 0.0f;
pairs= Dog - (cats + apples);
printf("pairs We have %f.",pairs);
printf("The milk is:");
scanf("%f",&milk);
pea = milk + Dog;
printf("OK!we can know %f is milk %f is pea!",milk,pea); /*去掉pea后面的.*/
}
改后
#include <stdio.h>
#define Dog 100
void main()
{
float cats = 10.0;
float apples = 20.0;
float pairs = 0.0;
float milk = 0.0;
float pea = 0.0;
pairs= Dog - (cats + apples);
printf("pairs We have %f.",pairs);
