的c語言程序代碼
兩種方法我寫在一起，可以獨立拆開。
#include <stdio.h>
void finda1(char a[3][10]);
void finda2(char a[3][10]);
void show(char (*p)[10]);
int main()
{
char a[3][10]={{"gehajl"},{"788a987a7"},{"ccabbbabbb"}};
printf("原數組內容: ");
show(a);
printf(" 1、用數組指針的方法（函數）： ");
finda1(a);
printf("執行後: ");
show(a);
printf(" --------------------- ");
char b[3][10]={{"gehajl"},{"788a987a7"},{"ccabbbabbb"}};
printf("原數組內容: ");
show(a);
printf(" 2、用指針數組的方法（函數finda2）： ");
finda2(b);
printf("執行後: ");
show(b);
return 0;
}
void finda1(char a[3][10])
{
int i,j;
char (*p)[10]=a;
for(i=0;i<3;i++)
for(j=0;j<10;j++)
if(p[i][j]=='a')
printf("發現：第%d行第%d個元素是『a』，已替換 ",i+1,j+1),p[i][j]='1';

『貳』 C語言編程代碼
我寫的是java手上沒有寫c的東西，思路就是把這個式子轉換成一步一步的普通式子就好了，既然你引用了math頭文件，裡面已經支持了各種各樣的計算方法，比如sin()，pow()等，運用這些方法分別計算：
1、計算 con3x + x平方 -1；
2、計算 e的x次方 - 2tanx + 1 取絕對值；
3、第1步與第2步求商；
4、計算 3ysiny + tany；
5、計算 1.5 + y的絕對值；
6、第4步與第5步求商；
7、第3步與第6步求和
『叄』 C語言，求程序代碼
#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』 求助五個C語言程序代碼
第一題:
#include
"stdio.h"
main()
{
int
a,b,c,k;
printf("請鍵入3個整數:");
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("調整後的a,b,c分別為:%d,%d,%d\n",a,b,c);

『捌』 求C語言源程序
用戶文檔：（1）每次輸入一個代號，執行一個操作，執行完後都回到界面，第一次執行操作時要先輸入若干個學升記錄。
（2）輸入時按學號由小到大以「學號，分數，名字」格式，學號在十位內，分數要是整數，名字不能有空格，每輸入一個學生記錄後按一次回車。
（3）加上插入的一共可存放20個學生。即：若一開始輸入5個學生記錄，則最多可插入15個學生記錄。
