1. Create a program that allocates an array of integers (as above), frees them, and then tries to print the value of one of the array elements. Does the program run? What does valgrind tell you?

answer:

the program runs fin, but val grind gives me an error. invalid read of size 4 which means it tried to read 4 bytes. it telles me that its an invalid address located right after a block of 400 free'd

1 #include 2 #include 3 4 int main(int argc, char *argv) 5 { 6 int *input = (int *) malloc(100 *sizeof(int) ); 7 *input = 100; 8 free(input) ; 9 printf("printing free data; %d\ ", *input); 10 return 0; 11 }
