Write a C program

Question

Suppose you have to develop small software to assist the primary students. Write a program that will help an elementary school student learn multiplication. Use the generatenumber 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.

Answer 1

#include <stdio.h>

#include <stdlib.h>

#include <time.h>

RandomProblem(int * a)

{

a[0] = rand()%10;

a[1] = rand()%10;

}

Go()

{

srand(time(NULL));

int a[2];

int answer;

while (1)

{

RandomProblem(a);

int done=0;

while (done==0)

{

printf(" What is %d times %d ???? :> ",a[0],a[1]);

scanf("%d",&answer);

if (answer==a[0]*a[1])

{

printf(" Very Good !!!! \n");

done=1;

}

else

{

printf(" Sorry, that is incorrect, try again ....\n");

}

}

}

}

int main()

{

Go();

}
