Question

Good evening,

I'm looking for some help on my C programming script.

I need it so each of the calculations on the sum is done by using "User defined functions"

I appreciate it in advance.

Using codeblocks.

#include <stdio.h>

int main()
{
int rowsize, i, j, sumofrow = 0, columnsum = 0, sum = 0, diagnalsum = 0;
int a[100][100];
printf("Enter how many rows are in your table: ");
scanf("%d", &rowsize);
printf("Enter how many elements ar: ");
for (i = 0; i < rowsize; i++) {
for (j = 0; j < rowsize; j++) {
scanf("%d", &a[i][j]);
}
}
for (i = 0; i < rowsize; i++) {
sumofrow = 0;
columnsum = 0;
for (j = 0; j < rowsize; j++) {
sumofrow += a[i][j];
columnsum += a[j][i];
}
printf("row%d: %d column%d: %d ", i + 1, sumofrow, i + 1, columnsum);
}
for (i = 0; i < rowsize; i++) {
for (j = 0; j < rowsize; j++) {
if (i == j) {
diagnalsum += a[i][j];
}
sum += a[i][j];
}
}
printf("Diagonal sum = %d ", diagnalsum);
printf("Total sum = %d ", sum);

return 0;
}

Explanation / Answer

#include <stdio.h>

// function 1

void calc(int a[][100], int rowsize)

{

int i,j,diagnalsum = 0, sum = 0;

for (i = 0; i < rowsize; i++) {

for (j = 0; j < rowsize; j++) {

if (i == j) {

diagnalsum += a[i][j];

}

sum += a[i][j];

}

}

printf("Diagonal sum = %d ", diagnalsum);

printf("Total sum = %d ", sum);

}

// function 2

void calculate(int a[][100], int rowsize)

{

int i, j, sumofrow, columnsum;

for (i = 0; i < rowsize; i++) {

sumofrow = 0;

columnsum = 0;

for (j = 0; j < rowsize; j++) {

sumofrow += a[i][j];

columnsum += a[j][i];

}

printf("row%d: %2d column%d: %d ", i + 1, sumofrow, i + 1, columnsum);

}

}

int main()

{

int rowsize, i, j, sumofrow = 0, columnsum = 0, sum = 0, diagnalsum = 0;

int a[100][100];

printf("Enter how many rows are in your table: ");

scanf("%d", &rowsize);

printf("Enter how many elements ar: ");

for (i = 0; i < rowsize; i++) {

for (j = 0; j < rowsize; j++) {

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

}

}

calculate(a,rowsize);

calc(a,rowsize);

return 0;

}

/*SAMPLE OUTPUT

Enter how many rows are in your table:

2

Enter how many elements ar:

1 2

3 4

row1: 3 column1: 4

row2: 7 column2: 6

Diagonal sum = 5

Total sum = 10
