Reading from user into array

[blackmustang01gt]

I am lost on my homework and need help .... here is what I am trying to do and the code I am working on is below it
Write a program for Matrix addition for two 3 by 3 matrices. -Take the input from the user. -Print both the input matrices and the output matrix.

#include<stdio. h>
main()
{
int aArray[3][3];
int bArray[3][3];
int cArray[3][3];
int a,b,c,d,e,f;

for(c = 0; c==2 ; c++)
{
for(d = 0; d==2 ;d++)
{
printf("enter values for Array 1: /n");
scanf("%d", aArray[c][d]);
}
}

for(e = 0; e==2;e++)
{
for(f = 0; f==2; f++)
{
printf("enter values for Array 2");
scanf("%d", bArray[e][f]);
}
}

for(a = 0; a==2;a++)
{
for(b = 0; b==2;b++)
{
cArray[a][b] = aArray[a][b] + bArray[a][b];
}
}

printf("%d\n", cArray);
}

int a,b,c,d,e,f;

You don't need all these variables, 2 will do the job, you can reuse them

for(c = 0; c==2 ; c++)

All your loops are like this, they don't work. This basically says, set c to 0, if c is equal to 2 continue executing the loop, at the end of each iteration increment c. As you can see the loop will never execute because c != 2 on the first attempt to run the loop. This would normally be written as

for(c = 0; c<3 ; c++)

Reading as set c to 0, if c is less than 3 continue executing the loop, at the end of each iteration increment c.

3 is a mgic number in your code, you should #define it.

It would be better if you indicated which element the input request was for by outputing c and d.

printf("%d\n", cArray);

This wont work, you will get the value of the pointer pointing at cArray. If you want to output the matrix then you will need to use 2 loops to get the value of every element and print it in the same way you use 2 loops to input every element and to do the addition.

#include<stdio. h>
main()
{
int N = 3;
int aArray[N][N];
int bArray[N][N];
int cArray[N][N];
int a,b;

for(a = 0; a!=N ; a++)
{
for(b = 0; b!=N ;b++)
{
printf("enter values for Array 1: /n");
scanf("%d", aArray[a][b]);
}
}

for(a = 0; a!=N;a++)
{
for(b = 0; b!=N; b++)
{
printf("enter values for Array 2");
scanf("%d", bArray[a][b]);
}
}

for(a = 0; a!=N;a++)
{
for(b = 0; b!=N;b++)
{
cArray[a][b] = aArray[a][b] + bArray[a][b];
}
}

printf("%d\n", cArray);
}
