# How to find the maximum element in the matrix using the function?

`````` #include<stdio.h>
int findMax(int **a,int r,int c);
int main()
{
int a[10][10],i,j,max,r,c;
printf("Enter the number of rows in the matrix\n");
scanf("%d",&r);
printf("Enter the number of columns in the matrix\n");
scanf("%d",&c);
printf("Enter the elements in the matrix\n");
for(i=1;i<=r;i++)
{  for(j=1;j<=c;j++)
scanf("%d",&[i][j]);
}
printf("The matrix is\n");
for(i=1;i<=r;i++)
{ for(j=1;j<=c;j++)
scanf("%d",&a[i][j]);
}printf("\n");}
max=findMax((int **)a,r,c);
printf("The maximum elements in the matrix is %d\n",max);
return 0;
}
int findMax(int **a,int r,int c)
{
int t,i,j;
t=a[1][1];
for(i=1;i<r;i++)
{ for(j=1;j<c;j++)
{ if(a[i][j]>t)
t=a[i][j];
}
}
return (t);
}
```
```

Here I attached my coding, I need to find the maximum element present in the matrix using function, I am doing the coding, calling function is not executed, I don't know why, Help me to figure it out.

Change

``````int findMax(int **a,int r,int c)
```
```

to

``````int findMax(int (*a)[10],int r,int c)
```
```

And also,

``````for(i=1;i<r;i++)
{
for(j=1;j<c;j++)
{
if(a[i][j]>t)
t=a[i][j];
}
}
```
```

to

``````for(i=1;i<=r;i++)
{
for(j=1;j<=c;j++)
{
if(a[i][j]>t)
t=a[i][j];
}
}
```
```

EDIT:

I think, your code should be like this:

``````#include<stdio.h>

int findMax(int (*a)[10],int r,int c);

int main()
{
int a[10][10],i,j,mx,r,c;
printf("Enter the number of rows in the matrix\n");
scanf("%d",&r);
printf("Enter the number of columns in the matrix\n");
scanf("%d",&c);
printf("Enter the elements in the matrix\n");

for(i=1;i<=r;i++)
{
for(j=1;j<=c;j++)
scanf("%d",&a[i][j]);
}
printf("The matrix is\n");
for(i=1;i<=r;i++)
{
for(j=1;j<=c;j++)
printf("%d ",a[i][j]);
printf("\n");
}
printf("\n");
mx=findMax(a,r,c);
printf("The maximum elements in the matrix is %d\n",mx);
return 0;
}

int findMax(int (*a)[10],int r,int c)
{
int t,i,j;
t=a[1][1];
for(i=1;i<=r;i++)
{
for(j=1;j<=c;j++)
{
if(a[i][j]>t)
t=a[i][j];
}
}
return (t);
}
```
```

Hope, it will help. :)
