Question

I created the following code using C programmming but for some reason its not running. Can you show me whats wrong.

#include <stdio.h>

void matrix_multiplication(int* left_matrix, int* right_matrix, int* result_matrix, int rows, int cols, int shared);

int main(void)
{
    int i,j,count=0;
  
    int matrix1[2][2];
    int matrix2[2][2];
    int matrix3[2][2];

Explanation / Answer

replace &matrix1 with (int*)matrix1 in the argument when you are calling the function, I have added the code below check it

#include <stdio.h>
void matrix_multiplication(int* left_matrix, int* right_matrix, int* result_matrix, int rows, int cols, int shared);
int main(void)
{
int i,j,count=0;
  
int matrix1[2][2];
int matrix2[2][2];
int matrix3[2][2];
  
printf("Matrix1 is: ");
for(i=0;i<2;i++) ///
{ ///
for(j=0;j<2;j++) ///
{ ///
count=count+3; ////----> initializing the first matrix1
matrix1[i][j]=count; //
printf("%5d",matrix1[i][j]);//
} //
printf(" ");
}
printf(" ");
count=0;
printf("Matrix2 is: ");
for(i=0;i<2;i++) ///
{ ///
for(j=0;j<2;j++) ///
{ ///----> initializing the first matrix2
count=count+4; //
matrix2[i][j]=count; //
printf("%5d",matrix2[i][j]);//
}
printf(" ");
}
printf(" ");
  
matrix_multiplication((int*)matrix1, (int*)matrix2,&matrix3[0][0], 0, 0, 2);//storing the multiplication for first row first column
  
matrix_multiplication((int*)matrix1, (int*)matrix2,&matrix3[0][1], 0, 1, 2);//storing the multiplication for first row second column

matrix_multiplication((int*)matrix1, (int*)matrix2,&matrix3[1][0], 1, 0, 2);//storing the multiplication for second row first column
  
matrix_multiplication((int*)matrix1, (int*)matrix2,&matrix3[1][1], 1, 1, 2);//storing the multiplication for second row second column
  
printf("The multiplication of matrix1 and matrix2 is: ");
for(i=0;i<2;i++) ///
{ ///

printf("%5d",matrix3[i][j]);///----> printing the result in matrix 3
} //
printf(" "); //
} //
return 0;
}
void matrix_multiplication(int* left_matrix, int* right_matrix, int* result_matrix, int rows, int cols, int shared)
{
int a,b,c,d;
  
if(rows==0 && cols==0)
{
