See this example!



int main( int argc, char ** argv )
{
    int *ptr = malloc(100 * sizeof (int));

    printf("sizeof(array) is %d bytes\n", sizeof(ptr));
}

The printf function return only 4 bytes! What is wrong?

Thanks so much!!!

I'm currently helping a friend debug a program of his, which includes linked lists. His list structure is pretty simple: typedef struct nodo{ int cantUnos; char* numBin; struct nodo* sig; }Nodo; We've got the following code snippet: void insNodo(Nodo** lista, char* auxBin, int auxCantUnos){ … >>> More

Hello, I am playing around with multidimensional array of unequal second dimension size. Lets assume that I need the following data structure: [&ptr0]-[0][1][2][3][4][5][6][7][8][9] [&ptr1]-[0][1][2] [&ptr2]-[0][1][2][3][4] int main() { int *a[3]; int *b; int i; a[0] = (int *)malloc(10… >>> More

I trying to allocate memory for 10 bytes BYTE* tmp; tmp = new BYTE[10]; //or tmp = (BYTE*)malloc(10*sizeof(BYTE)); But after new or malloc operation length of *tmp more than 10 (i.e. '\0' char not in 10 position in tmp array) Why? >>> More

Hi all, I just started out with C and have very little knowledge about performance issues with malloc() and free(). My question is as such: if I were to call malloc() followed by free() in a while-loop that loops for, say, 20 times, would it run slower compared to if I were to call free() outside… >>> More

I am a beginner in C. While reading git's source code, I found this wrapper function around malloc. void *xmalloc(size_t size) { void *ret = malloc(size); if (!ret && !size) ret = malloc(1); if (!ret) { release_pack_memory(size, -1); ret = malloc(size); … >>> More
