C program to find sum of upper triangle matrix; Through this tutorial, we will learn how to calculate sum of upper triangle matrix in the c program.
C Program to Find Sum of Upper Triangle Matrix
/* C Program to find Sum of Upper Triangle Matrix */
#include<stdio.h>
int main()
{
int i, j, rows, columns, a[10][10], Sum = 0;
printf("\n Please Enter Number of rows and columns : ");
scanf("%d %d", &i, &j);
printf("\n Please Enter the Matrix Elements \n");
for(rows = 0; rows < i; rows++)
{
for(columns = 0;columns < j;columns++)
{
scanf("%d", &a[rows][columns]);
}
}
for(rows = 0; rows < i; rows++)
{
for(columns = 0; columns < j; columns++)
{
if(columns > rows)
{
Sum = Sum + a[rows][columns];
}
}
}
printf("\n The Sum of Upper Triangle Matrix = %d", Sum);
return 0;
}
The output of the above c program; as follows:
Please Enter Number of rows and columns : 3 3 Please Enter the Matrix Elements 1 2 3 4 5 6 7 8 9 The Sum of Upper Triangle Matrix = 11
