Write a program to determine whether or not the given square is a magic square?
/*This program takes a square matrix from user and check whether it's a Magic Square or not. */ #include<stdio.h> #include<conio.h> int num[10][10],sum[21],r,c,i=0,x; void read_matrix() { for(r=0;r<x;r++) { for(c=0;c<x;c++) { printf("Enter the value of matrix[%d][%d] :",r,c); scanf("%d",&num[r][c]); } } } void calculate_sum() { int sum_row,sum_col=0,ctr=0; for(r=0;r<x;r++) { sum_row = 0; for(c=0;c<x;c++) { printf("\t%d",num[r][c]); sum_row = sum_row + num[r][c]; } sum[ctr] = sum_row; ctr++; printf(":: %d",sum_row); printf("\n"); } while(i<x) { printf("\t::"); i++; } printf("\n"); for(c=0;c<x;c++) {sum_col = 0; for(r=0;r<x;r++) sum_col = sum_col + num[r][c]; sum[ctr] = sum_col; ctr++; printf("\t%d",sum_col); } for(r=0,c=0;r<x;r++,c++) sum[2*x] = sum[2*x] + num[r][c]; for(r=0,c=x-1;r<x;r++,c--) sum[2*x+1] = sum[2*x+1] + num[r][c]; } char check_matrix() { char c; for(i=0;i<2*x+1;i++) { if(sum[i] == sum[i+1]) c = 'Y'; else { c = 'N'; break; } } return c; } void main() { char c; clrscr(); printf("Enter d no. of rows or cols u want in your matrix :"); scanf("%d",&x); read_matrix(); calculate_sum(); c = check_matrix(); if(c=='Y') printf("\nThis matrix is a Magic Square"); else printf("\nThis matrix is not a Magic Square"); getch(); }
What is 16ft x 4ft in square meters?
Oh, dude, you're hitting me with the math questions now? Okay, okay, let me just dust off my calculator real quick... So, 16ft x 4ft is 64 square feet. To convert that to square meters, you divide by 10.764, which gives you approximately 5.95 square meters. Voilà! Math magic, like a wizard with numbers.
What is the area of a square whose sides are 15 cm?
Oh, dude, it's like super easy. So, to find the area of a square, you just multiply the length of one side by itself. In this case, 15 cm times 15 cm gives you an area of 225 square cm. Boom, math magic!
How many square meters in 9ft x 15ft?
Alright, buckle up, buttercup. To convert feet to meters, you divide by 3.281. So, 9ft is approximately 2.74m and 15ft is about 4.57m. Multiply those two numbers together and you get roughly 12.48 square meters. Voilà, math magic!
How can you find the side length of a square if you know it's area?
The area of a square is one side multiplied by an adjacent side. In a square all sides are the same length. Then the square root of the area must be the length of any side. If you know the area you can look up the square root in tables found in many older math books, or simply find the square on your calculator.

What is the sum in the 1st row of the 8x8 magic square?
In an 8x8 magic square, the sum of each row, column, and diagonal is the same, known as the magic constant. For an n x n magic square, the magic constant can be calculated using the formula ( M = \frac{n(n^2 + 1)}{2} ). For an 8x8 magic square, this gives ( M = \frac{8(64 + 1)}{2} = 260 ). Therefore, the sum in the 1st row of an 8x8 magic square is 260.

Take any valid 4 x 4 magic square. For example: 9 6 3 16 4 15 10 5 14 1 8 11 7 1 10 16 Decrease every number by 6, so that the smallest number you will find in the square is -5, and the largest number in the square will be 10. This is a valid magic square for the set of numbers given and can be rotated any of four ways, and reflected either of two ways.
