FOLLOW DIRECTIONS USING \"C\" ONLY MUST USE \"FOR\" LOOP AND MULTIDIMENSIONAL AR

Question

FOLLOW DIRECTIONS USING "C" ONLY MUST USE "FOR" LOOP AND MULTIDIMENSIONAL ARRAY ILL RATE POORLY IF DIRECTIONS NOT FOLLOWED nsion of a n x n matrix (ask the value for "n"), take rix, then compute the sum of all upper diagonal 3. Create a script that will prompt the user the o all the user input for the individual entry of the elements and the sum of all lower diagonal eiements You need to use Multidimensional Array and For to use loops. 3 4] Upper Diagonal Line 13 14 15 16 Lower Diagonal Line For this matrix, since n is 4, the user should be prompted 17 times (Once for n value, and 16 times for the entries of the matrix-nxn times). The sum of Upper Diagonal Line should be 2+7+12 -21 and the sum of Lower Diagonal Line should be 5+10+15-30

Explanation / Answer

#include<stdio.h>

#include<conio.h>

void main()

{

int n,i,j, U_diag_sum, L_diag_sum, A[10][10];

U_diag_sum=0;

L_diag_sum=0;

printf(" Enter size of the matrix : ");

scanf("%d",&n);

/* Storing elements in the matrix */

printf(" Enter elements of the matrix: ");

for(i=0;i<n;i++)

for(j=0;j<n;j++)

{

printf(" Enter element a%d%d: ",i,j);

scanf("%d", &A[i][j]);

}

/* Calculating upper diagonal sum */

for(i=0;i<n;i++)

for(j=0;j<n;j++)

{

if(j-i==1)

U_diag_sum=U_diag_sum+A[i][j];

}

printf(" Upper diagonal sum = %d", U_diag_sum);

/* Calculating lower diagonal sum */

for(i=0;i<n;i++)

for(j=0;j<n;j++)

{

if(i-j==1)

L_diag_sum=L_diag_sum+A[i][j];

}

printf(" Lower diagonal sum=%d",L_diag_sum);

getch();

}
