C++ Program
1. Prompt the user to enter the size of the square such as N. N must be greater than or equal to 2 and less than or equal to 10.
2. create an array of size N x N.
3. use the fucntion to popuate the array with distinct random numbers that are between 1 - 100.
4. use a function to determine whether the numbers in N x N are magic square numbers.
5. repeat steps 1 - 4 until the user termiates the program.
Magic Number : n(n2 + 1) / 2
the program must have rows and colums that all equate to the sum of 15 for example
8 1 6 = 15
3 5 7 = 15
4 9 2 = 15
ask the user if he would like to enter another magic square and compute the same way. (Y/N)
this is a sample report of the output
Welcome to my magic sequence program The function of the program is to 1, Allow the user to enter the size of the magic square such as N . N>= 2 andExplanation / Answer
#include<stdio.h>
int main() {
int size,N;
char ans;
printf("enter size of the magic square");
scanf("%d",&N);
if((N<2)&&(N>10))
{
printf(" Please enter a range between 2 to 10");
}
size = N;
int matrix[N][N]; // = {{4,9,2},{3,5,7},{8,1,6}};
int r, c = 0;
int sum, sum1, sum2;
int flag = 0;
printf(" Enter Random numbers ");
for (r = 0; r < size; r++) {
for (c = 0; c < size; c++)
scanf("%d", &matrix[r][c]);
}
printf(" matrix that is created for test is : ");
for (r = 0; r < size; r++) {
printf(" ");
for (c = 0; c < size; c++) {
printf(" %d", matrix[r][c]);
}
}
//For diagonal elements
sum = 0;
for (r = 0; r < size; r++) {
for (c = 0; c < size; c++) {
if (r == c)
sum = sum + matrix[r][c];
}
}
//For Rows sums to be compared
for (r = 0; r < size; r++) {
sum1 = 0;
for (c = 0; c < size; c++) {
sum1 = sum1 + matrix[r][c];
}
if (sum == sum1)
{
flag = 1;
printf(" sum of %d th row %d",r+1,sum1);
}
else {
flag = 0;
break;
}
}
//For Columns sums to be compared
for (r = 0; r < size; r++) {
sum2 = 0;
for (c = 0; c < size; c++) {
sum2 = sum2 + matrix[c][r];
}
if (sum == sum2)
{
flag = 1;
printf(" sum of %d th column %d",c+1,sum2);
}
else {
flag = 0;
break;
}
}
if (flag == 1)
printf(" Magic square");
else
printf(" Not a Magic square");
return 0;
}
