C program to find the trace of a matrix; Through this tutorial, we will learn how to find the trace of a matrix using for loop, while loop and do while loop in c programs.
Programs to Find the Trace of a Matrix in C
- C Program to Find the Trace of a Matrix using For Loop
- C Program to Find the Trace of a Matrix using While Loop
- C Program to Find the Trace of a Matrix using Do While Loop
C Program to Find the Trace of a Matrix using For Loop
#include <stdio.h>
int main()
{
int i, j, rows, columns, trace = 0;
printf("Enter Matrix Rows and Columns = ");
scanf("%d %d", &rows, &columns);
int Tra_arr[rows][columns];
printf("Please Enter the Matrix Items = \n");
for (i = 0; i < rows; i++)
{
for (j = 0; j < columns; j++)
{
scanf("%d", &Tra_arr[i][j]);
}
}
for (i = 0; i < rows; i++)
{
for (j = 0; j < columns; j++)
{
if (i == j)
{
trace = trace + Tra_arr[i][j];
}
}
}
printf("The Trace Of the Matrix = %d\n", trace);
}
The output of the above c program; is as follows:
Enter Matrix Rows and Columns = 2 2 Please Enter the Matrix Items = 1 2 3 4 The Trace Of the Matrix = 5
C Program to Find the Trace of a Matrix using While Loop
#include <stdio.h>
int main()
{
int i, j, rows, columns, trace = 0;
printf("Enter Matrix Rows and Columns = ");
scanf("%d %d", &rows, &columns);
int Tra_arr[rows][columns];
printf("Please Enter the Matrix Items = \n");
i = 0;
while(i < rows)
{
j = 0;
while(j < columns)
{
scanf("%d", &Tra_arr[i][j]);
j++;
}
i++;
}
i = 0;
while(i < rows)
{
j = 0;
while(j < columns)
{
if(i == j)
{
trace = trace + Tra_arr[i][j];
}
j++;
}
i++;
}
printf("The Trace Of the Matrix = %d\n", trace);
}
The output of the above c program; is as follows:
Enter Matrix Rows and Columns = 2 2 Please Enter the Matrix Items = 3 4 5 6 The Trace Of the Matrix = 9
C Program to Find the Trace of a Matrix using Do While Loop
#include <stdio.h>
int main()
{
int i, j, rows, columns, trace = 0;
printf("Enter Matrix Rows and Columns = ");
scanf("%d %d", &rows, &columns);
int Tra_arr[rows][columns];
printf("Please Enter the Matrix Items = \n");
i = 0;
do
{
j = 0;
do
{
scanf("%d", &Tra_arr[i][j]);
if (i == j)
{
trace = trace + Tra_arr[i][j];
}
} while (++j < columns);
} while (++i < rows);
printf("The Trace Of the Matrix = %d\n", trace);
}
The output of the above c program; is as follows:
Enter Matrix Rows and Columns = 2 2 Please Enter the Matrix Items = 5 6 7 8 The Trace Of the Matrix = 13
