2. 高手帮忙改一个c语言程序

int sfz(int a)
{
int a;
a=3;
return a+5;
}
int main()
(
 int x;
 scanf("%d",&x);
 printf("is %d",sfz(x));
return 0;
) 


这段程序的主要问题在于没有实参。
少一个输入语句，或者你给x赋值也可以

4. 求一C语言程序，哪位高手帮忙解决一下。

#include "stdio.h"

void cin(int *p)
{
 int i;
 printf("请输入十个整数：\n");
 for(i=0;i<10;i++)
 {
  scanf("%d",&p[i]);
 }
}
void swap(int *p)
{
 int i,temp,min,max,min1,max1;
 min=p[0];
 max=p[0];
 for(i=1;i<10;i++)
 {
  if(min>p[i])
  {
   min=p[i];
   min1=i;
  }
  if(max<p[i])
  {
   max=p[i];
   max1=i;
  }
 }
 p[min1]=p[0];
 p[0]=min;
 p[max1]=p[9];
 p[9]=max;
}
void print(int *p)
{
 int i;
 for(i=0;i<10;i++)
 {
  printf("%d\t",p[i]);
 }
}
int main(int argc, char* argv[])
{
 int array[10];
 int *p=array;
 cin(p);
 swap(p);
 print(p);
 return 0;
}

5. C语言程序改错，望高手帮忙，谢谢！

楼上说得对，是函数的形式参数和调用的实际参数不符合。
sort(4,data[1]);
这里调用sort的是两个整形的实际参数
而sort(int n,int array[])
定义部分是一个整形和一个数组形式参数，两者不匹配。 
应把调用改为
sort(4,data);

6. 请c语言高手帮忙写一个C语言程序

#include 

int main(void)
{
  char c;
  for (c=33;c<=126;++c)
   printf("%d\t%o\t%x\t%c\n",c,c,c,c);
  return 0;
}

7. 请高手帮忙编一个C语言程序

//---------------------------------------------------------------------------

#include 

void fun(int a[][5],int size)
{
 int i,j,t;
 for (i = 0; i<size; i++) {
  for (j=i+1; j<5; j++) {
   t=a[i][j];
   a[i][j]=a[j][i];
   a[j][i]=t;
  }
 }
}
int main(void)
{
 int i,a[5][5];
 for (i = 0; i<25; i++) {      /*为5*5矩阵赋初值并输出*/
  a[i/5][i%5]=i;
  printf("%-2d ",a[i/5][i%5]);
  if ((i+1)%5==0) putchar('\n');
 }
 fun(a,5);                    /*转置*/
 puts("Transpose:") ;
 for (i = 0; i<25; i++) {      /*输出转置后的矩阵*/
  printf("%d ",a[i/5][i%5]);
  if ((i+1)%5==0) putchar('\n');
 }
 return 0;
}

8. c语言程序：高手帮忙了！

按照题目，第一个人拿1个，第二个人拿2个，最后一个人是第n个，他必须拿n块吧。当然相等了。。
