5：在包含10个数的一维整数数组a中查找给定的数据num。如果找到则返回1,未找到返回 0 .

include <fstream.h>#include <iostream.h>int fun(int a[],int num){/**********Program**********/for(int i=0;i<10;i++){if(a[i]==num)return 1;}return 0;/**********  End  **********/}void main(){           int a[10]={54,256,563,754,34,56,345,543,45,65};       int num = 46;           if (fun(a,num)==1)                        cout <<" 找到！" <<endl;           else            cout <<" 没有找到！" <<endl;           void wwjt();           wwjt();}void wwjt(){      int a[10]={54,256,563,754,34,56,345,543,45,65};                          fstream myfile;                myfile.open(" out.txt" ,ios::out);                myfile<<fun(a,46)<<endl;                myfile<<fun(a,345)<<endl;                myfile.close();}

8：将数组S中所有小写字母改写成大写字母。

#include <iostream.h>#include <fstream.h>#include <string.h>void fun(char s[]){/**********Program**********/for(int i=0;i<80;i++){if(s[i]>'Z')s[i]=s[i]-32;cout<<s[i];}/**********  End  **********/        }void wwjt(char []);void main(){        char s[80] = " abdsaFDSAFdsafASFDSafghHFDHTjte" ;        fun(s);            wwjt(s);}void wwjt(char s[]){        fstream myfile;        myfile.open(" out.dat" ,ios::out);        myfile<<s<<endl;        myfile.close();}
