Question

The use of computers in education is referred to as computer- assisted instruction ( CAI). Write a program that will help an elementary school student learn multiplication. Use the rand function to produce two positive one- digit integers. The program should then prompt the user with a question, such as
How much is 6 times 7?
The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message " Very good!" and ask another multiplication question. If the answer is wrong, display the message " No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate function should be used to generate each new question. This function should be called once when the application begins execution and each time the user answers the question correctly.

Explanation / Answer

please rate - thanks

#include<stdio.h>
#include<conio.h>
int problem(int*,int*);
int main()
{int x,y,answer,correct;
srand(time(0));
do{correct=problem(&x,&y);        
   do
     {
       printf("How much is %d times %d =",x,y);
       scanf("%d",&answer);
       if(answer!=correct)
           printf("No, please try again ");
     }while(answer!=correct);
   printf("Very Good ");
}while(1);

return 0;
}
int problem(int* x,int* y)
{int correct;
*x=rand() % 10;
   *y=rand() % 10;
   correct=*x**y;
return correct;
}
