C programming I'm trying to fix memory leak but it kept giving that one error. Where did I go wrong? #include #include void printArray(int *arr, int size){ int i; if (arr != NULL) { for( i = 0; i < size; i++) { // Print each element out printf("%d", *(arr+i)); //Print addresses of each element printf("%p", (arr+i)); //Printing a new line printf("\n"); } } } int main() { // Allows user to specify the original array size, stored in variable n1. printf("Enter original array size: "); int n1 = 0; scanf("%d", &n1); //a- Create a new array *a1 of n1 ints using malloc int *a1 = malloc(n1 * sizeof(int)); //b- Remove comments for if statment below //b- Set each element in a1 to 100 + indexValue ?? if(a1 == NULL) { printf("Error! memory not allocated."); exit(0); } int i; for (i = 0; i < n1; i++) { a1[i] = 100 + i; } printf("Printing the first array allocated using malloc\n"); //c- Print each element and addresses out (to make sure things look right) printArray(a1, n1); // User specifies the new array size, stored in variable n2. printf("\nEnter new array size: "); int n2 = 0; scanf("%d", &n2); //d- Dynamically change the array a1 to size n2 a1 = malloc (n2 * sizeof(int)); //e- Remove comments for if statment below if(a1 == NULL) { printf("Error! memory not allocated."); exit(0); } //e- If the new array is a larger size, set all new members to 200 + indexValue. if (n2 > n1) { int i; for (i = 0; i < n2; i++) { a1[i] = 100 + i; } } printf("Printing the reallocated array: \n"); //f- Print each element and addresses out (to make sure things look right) printArray(a1, n2); //g-Free the allocated memory for a1 free(a1); a1 = NULL; printf("\nEnter new array size to be initialized with 0: "); int n3 = 0; scanf("%d", &n3); //h- Remove comments for if statement //h- Using calloc create a new array and assign it to a2 //with new array size, stored in variable n3. int *a2 =calloc(n3, sizeof(int)); if(a2 == NULL) { printf("Error! memory not allocated."); exit(0); } printf("Printing the array created using calloc: \n"); //i- Print array a2 with size n3 printArray(a2, n3); //j- Print array a1 again, How you can fix this problem printf("Printing deallocated array a1: \n"); printArray(a1, n2); // Done with arrays now, free the and assign NULL free(a2); a1 = NULL; a2 = NULL; printf("Program Successfully Completed!"); return 0; }
