i allocate memory for b_edge in function bark_edge and give value to only b_edge[1][1] and try to return b_edge from function. segmentation fault comes? can you please check why?
//function bark_edge+main program
#include<stdio.h>
#include<math.h>
#include<stdlib.h>
double **bark_edge();
main()
{
double **b_edge;
b_edge=bark_edge();
printf("%f",b_edge[1][1]);
}
//FUNCTION-bark_edge
double **bark_edge()
{
int i=0;
double **b_edge;
//memory allocation for b_edge
b_edge = (double**)malloc(10* sizeof(double *));
if(b_edge== NULL)
{
printf("out of memory\n");
return 0;
}
for(i = 0; i <1024 ; i++)
{
b_edge[i] = (double*)malloc(10 * sizeof(double));
if(b_edge[i] == NULL)
{
printf("out of memory\n");
return 0;
}
}
b_edge[1][1]=2;
return b_edge;
}
