两种方法我写在一起，可以独立拆开。
#include <stdio.h>

void finda2(char a[3][10]);

printf("原数组内容: ");
show(a);
printf(" 1、用数组指针的方法（函数）： ");
finda1(a);
printf("执行后: ");
show(a);
printf(" --------------------- ");

『贰』 C语言编程代码
我写的是java手上没有写c的东西，思路就是把这个式子转换成一步一步的普通式子就好了，既然你引用了math头文件，里面已经支持了各种各样的计算方法，比如sin()，pow()等，运用这些方法分别计算：
1、计算 con3x + x平方 -1；
2、计算 e的x次方 - 2tanx + 1 取绝对值；
3、第1步与第2步求商；
4、计算 3ysiny + tany；
5、计算 1.5 + y的绝对值；
6、第4步与第5步求商；
7、第3步与第6步求和
『叁』 C语言，求程序代码
#include<stdio.h>
int main()
{ char s[100],*p,*q;
gets(s);
for(p=q=s;*p;p++)
if(*p>='0'&&*p<='9'||*p>='A'&&*p<='F'||*p>='a'&&*p<='f')
*q++=*p;
*q=' ';
puts(s);
return 0;
}
『肆』 求助五个C语言程序代码
第一题:
#include

main()
{
int
a,b,c,k;
printf("请键入3个整数:");
scanf("%d%d%d",&a,&b,&c);
if(a>b){k=a;a=b;b=k;}
if(a>c){k=a;a=c;c=k;}
if(b>c){k=b;b=c;c=k;}
printf("调整后的a,b,c分别为:%d,%d,%d\n",a,b,c);

『捌』 求C语言源程序
用户文档：（1）每次输入一个代号，执行一个操作，执行完后都回到界面，第一次执行操作时要先输入若干个学升记录。
（2）输入时按学号由小到大以“学号，分数，名字”格式，学号在十位内，分数要是整数，名字不能有空格，每输入一个学生记录后按一次回车。
（3）加上插入的一共可存放20个学生。即：若一开始输入5个学生记录，则最多可插入15个学生记录。
