a[minPos] = temp; }

main() {

int a[ARRSIZE],i;

printf(\

for (i=0; i

scanf(\

MaxMinExchang(a, ARRSIZE);

printf(\

for (i=0;i

printf(\

printf(\ }

5. 写一函数，能对给定的一个二维数组（3×3）进行转置（即行列互换）。

#include

#define N 3

int array[N][N];

void main()

{ void convert(int array[][3]);

int i,j;

printf(\

for (i=0;i

for (j=0;j

scanf(\

printf(\

for (i=0;i

{for (j=0;j

printf(\

printf(\ }

convert(array);

printf(\

for (i=0;i

{for (j=0;j

printf(\

printf(\ } }

void convert(int array[][3])

{int i,j,t;

for (i=0;i

for (j=i+1;j

{t=array[i][j];

array[i][j]=array[j][i];

array[j][i]=t;

} }

6. 写一函数，能用“起泡法”对输入的10个字符按由小到大顺序排序。

#include

#include

#define N 10

char str[N];

void main()

{void sort(char str[]);

int i,flag;

for (flag=1;flag==1;)

{printf(\

scanf(\

if (strlen(str)>N)

printf(\ else

flag=0;

}

sort(str);

printf(\

for (i=0;i

printf(\

printf(\ }

void sort(char str[])

{int i,j;

char t;

for(j=0;j

for (i=0;(i

if(str[i]>str[i+1])

{t=str[i];

str[i]=str[i+1];

str[i+1]=t;

} }

7. 编写一个函数，由实参传来一个字符串，统计此字符串中字母、数字、空格和其他字符的个数。

#include

int letter,digit,space,others;

void main()

{void count(char str[]);

char text[80];

printf(\

gets(text);

printf(\

puts(text);

letter=0;

digit=0;

space=0;

others=0;

count(text);

printf(\ }

void count(char str[])

{int i;

for (i=0;str[i]!='\\0';i++)

if ((str[i]>='a'&& str[i]<='z')||(str[i]>='A' && str[i]<='Z'))

letter++;
