Dynamic Memory Allocation

A call to malloc() prototype: void* malloc(size in bytes); example: int* ptr = malloc(sizeof(int) * 10);

Check for NULL! int* ptr = malloc(sizeof(int) * 10); if (ptr == NULL) { printf("Error -- out of memory.\n"); return 1; }

A call to free()

prototype: void free(pointer to heap memory); example: free(ptr);

#include #include int main(void) { int* ptr = malloc(sizeof(int)); if (ptr == NULL) { printf("Error -- out of memory.\n"); return 1; } *ptr = GetInt(); printf("You entered %d.\n", *ptr); free(ptr); }

Dynamic Memory Allocation

int main(void). { int* ptr = malloc(sizeof(int)); if (ptr == NULL). { printf("Error -- out of memory.\n"); return 1;. } *ptr = GetInt(); printf("You entered %d.\n", *ptr); free(ptr);.
