介绍C程设计的一典型案例：例如编写一些小游戏

#include<stdio.h>
int main(void)
{
	int i,n,grade,A,B,C,D,E,F;
	A=0;
	B=0;
	C=0;
	D=0;
	E=0;
	F=0;
	printf("Enter n:");
	scanf("%d",&n);
	for(i=1;i<=n;i++)
	{
		printf("Enter grade %d:",i);
		scanf("%d",&grade);
		if(grade<0)
		{
			F++;
		}
		else if(grade<=100&&grade>=90)
		{
			A++;
		}
		else if(grade<=89&&grade>=80)
		{
			B++;
		}
		else if(grade<=79&&grade>=70)
		{
			C++;
		}
		else if(grade<=69&&grade>=60)
		{
			D++;
		}
		else
		{
			E++;
		}
	}
	printf("The number of A(90~100):%d\nThe number of B(80~89):%d\nThe number of C(70~79):%d\nThe number of D(60~69):%d\nThe number of E(0~59):%d\nThe fault grade is:%d\n",A,B,C,D,E,F);
	return 0;
}
