how to convert both letters of a comparison to a common representation
before testing their equality (i.e. convert both letters to upper case before comparing them).

How do I write an input and output file that stores informtion

while(select !=5)
{
DisplayMatrixA();

printf("(1)Set matrix A:\n ");
printf("(2)Add a matrix B:\n ");
printf("(3)Multiply with a matrix B:\n ");
...

/*Matrix*/

#include<stdio.h>
int i=0;
int j=0;
int k=0;
int col=3;
int row=3;
int rowb=0;
int t;

/code/
/* Matrix */

#include <stdio.h>

void SetMatrixA();
void AddMatrixBtoA();
void DisplayMatrixA();
void MultiplyMatrixBtoA();
void TransposeMatrixA();

/* Matrix */

#include <stdio.h>

void SetMatrixA();
void AddMatrixBtoA();
void DisplayMatrixA();
void MultiplyMatrixBtoA();
void TransposeMatrixA();
int rowsA;

/code/
double A[5][5];
int columnsA = 3;
int rowsA = 3;

void setmatrix(double MA[5][5])
{
int i;
int j;
