Im C please Identify fix and explain what errors if any exis

Identify, fix. and explain what errors, if any. exist within the two main programs. int main(void) {int* p = maIIoc(42); char* q = (char*) p; strcpy(q. \"random string\"); *p = 65;} int main(void) {int* p = (int*) malloc(sizeof(int)); int* q = p; *p = 42; frce(p); frec(q); *p = 9; struct node {int value; struct node* next; Write the following function: struct node * find_last (struct node* list, int n); The list parameter points to a linked list. The function should return a pointer to the last node that contains n; it should return NULL if n does not appear in the list.

Solution

Please follow the code and comments for description :

3)

a)

CODE :

After the inclusion of the necessary header files to the code the execution and the compilation of the program is perfect.

#include <stdio.h> // required header files
#include <string.h>
#include <stdlib.h>

int main(void) // main driver method
{
    int *p = malloc(42); // allocating the value to the pointer
    char * q = (char*)p; // pointer declaration and initialisation
    strcpy(q, \"random string\"); // copying the string
    *p = 65; // pointer setting to a value of index
}

b)

CODE :

After the inclusion of the necessary header files to the code the execution and the compilation of the program is perfect

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main(void)
{
    int *p = (int*)malloc(sizeof(int));
    int *q = p;
    *p = 42;
    free(p);
    free(q);
    *p = 9;
}

Hope this is helpful.
