第一部分：
#include

main()
{
int s,i;
s=0;
for(i=0;5*i+4<=1001;i++)
{
s+=5*i+4;
}
printf("%d\n",s);
}

第二部分：
#include

main()
{
int n,i,j;
printf("Input n:");
scanf("%d",&n);
for(i=n;i>0;i--)
{
for(j=0;j printf("*");
printf("\n");
}
}

第三部分：
#include

main()
{
int n,s,i,t;
printf("Input n:");
scanf("%d",&n);
t=1;
s=0;
for(i=1;i<=n;i++)
{
t*=i;
s+=t;
}
printf("s=%d\n",s);
}

第四部分：
#include
#include
main()
{
int option=0; /*选择用变量,use to record user's press*/
float celsius; /*摄氏温度,she shi wen du*/
float fahrenheit; /*华氏温度,hua shi wen du*/

while(option!=3)
{
printf("1 for Fahrenheit to Celsius;\n");
printf("2 for Celsius to Fahrenheit;\n");
printf("3 to quit.\n");
printf("Please to choose: ");

scanf("%d",&option);
printf("\n");
if(option==1)
{
scanf("%f",&fahrenheit);
celsius=(fahrenheit-32)*5/9;
printf("The Fahrenheit %f in Celsius is %f\n",fahrenheit,celsius);
}

if(option==2)
{
scanf("%f",&celsius);
fahrenheit=(celsius*9/5)+32;
printf("The Celsius %f in Fahrenheit is %f\n",celsius,fahrenheit);
}

printf("Press any key to continue...\n");
getch(); /*pause for screen, press any key to continue*/
clrscr();
}/*end While*/

}/*end main*/
