程式一為：

#include

void main()

{

int a,b,c,s;

cout

cin>>a>>b;

s=a+b;

cout

cout

cin>>c;

if(c==s)

cout

else

cout

}

程式二為：#include

void main()

{

int a,b,c,s;

cout

cin>>a>>b;

s=a+b;

cout

cout

cin>>c;

while(c!=s)

{

cout

cout

cin>>c;

}

cout

}

程式三為：#include

void main()

{

int a,b,c,s,n;

cout

cin>>a>>b;

s=a+b;

cout

cout

cin>>c;

for(n=1;n

{

if(c!=s)

{

cout

cout

cin>>c;

n++;

}

else

cout

break;

}

cout

}

程式四為：#include

#include

#include

using namespace std;

void main()

{

int a,b,c,s,n=0,m,k,z;

for(int i=1;i

{

cout

int j= rand();

int k= rand();

a=j%10;

b=k%10;

cout

s=a+b;

cout

cout

cin>>c;

if(c==s)

{

cout

n++;

}

else

cout

}

m=10-n;

k=10*n;

cout

cout

}

這幾個我都除錯過了，沒問題的！
