int e,f;
FILE *file;
char buffer[128];
char *token;
int n,m;
char *a[10][10];
int i=0,j;
void find_keyword()
{
while(fgets(buffer,128,file) != NULL)
{
token = strtok(buffer,",");
j=0;
while(token != NULL)
{
a[i][j]=strdup(token);
printf("a[%d][%d]=%s\t",i,j,a[i][j]);
token = strtok(NULL,",");
j++;
}
i++;
}

void main ()
{
printf("Enter the values of m and n?\n");
scanf("%d",&m);
scanf("%d",&n);
