The dummy code looks some thing like this: #define TOTAL_NO_OF_PIXEL 1080 //For example total 1080 no of pixels are there int RGBcolor[3][TOTAL_NO_OF_PIXEL]; int main() { for(int cnt=0;cnt<TOTAL_NO_OF_PIXEL;cnt++) { RGBcolor[0][cnt] = RED; RGBcolor[1][cnt] = GREEN; … Read more

[Solved] free() not working correctly with struct

by

[ad_1] It is always a good habit to set the pointer to NULL after freeing it. Since the memory you are accessing is still intact you are seeing right values for l->val. Node *l=malloc(sizeof(Node)); l->key=”foo”; l->val=”bar”; free(l); l = NULL; [ad_2] solved free() not working correctly with struct
