网站上机程序参考源代码

1. 编程题1:sizeof测试字节数

#include int main() {

printf(\ printf(\ printf(\ printf(\

printf(\ printf(\ printf(\ return 0; }

2. 编程题2:输入/输出练习

#include int main() {

int a=20; float b; double c; b=12.345f;

scanf(\ printf(\ printf(\ printf(\ return 0; }

3. 编程题3：用if语句求解分段函数 #include int main( ) { double x,y; scanf(\ if (x<20) y=x+100; else if (x<=100) y=x; else y=x-100; printf(\ return 0; }

4. 编程题4：打印每月有几天

#include int main( )

{ int year,month,day; scanf(\ switch(month) { case 1: case 3: case 5: case 7: case 8: case 10: case 12: day=31; break; case 4: case 6: case 9: case 11: day=30; break; case 2: day=28; if (year%4==0&&year0!=0||year@0==0) day=29; break; default: printf(\ }

5. 编程题5：输出所有的3位数字的质数 #include #include int main() { int m,i,k,prime,count=0; for (m=101;m<999;m=m+2) { k=(int)sqrt(m); prime=1; for (i=2;prime&&i<=k;i++) if (m%i==0) prime=0; if (prime) { printf(\ count++; if (count%5==0) printf(\ } } printf(\ return 0; }

6. 编程题6：数列求和 #include #include int main( ) { double x,term=1,i=1,sum=0; int sign=1; scanf(\ do { term=term*x/i; sum+=sign*term; sign=-sign; i++; }while(fabs(term)>=1e-5); printf(\ return 0; }

7. 编程题7：求平均值 #include int main( ) { int i,a[20],max,min,sum=0,count=0; for (i=0;i<20;i++) scanf(\ max=min=a[0]; for (i=0;i<20;i++) if (a[i]>max) max=a[i]; else if(a[i]

8. 编程题8：用数组实现Fibonacci数列 #include int main( ) { int n,f[40],i; do{

scanf(\ }while (n<=0||n>40); f[0]=f[1]=1; for (i=2;i

9. 编程题9：删除所有相同值的元素

#include

int main( ) {

int a[20];

int i=0,j,x,total=0,s=0; do

{ scanf(\ }while(a[i-1]);

s=total=i; scanf(\ printf(\ for (i=0;i

printf(\ printf(\

for (i=0;i

while (i

for (j=i;j

printf(\ for (i=0;i

printf(\ printf(\
