program to understand struct pointer using typedef

//understanding struct pointer with typedef
#include <stdio.h>
#include <stdlib.h>
typedef struct reco
{
    int a;
    float b;
    char c;
    char city[100];
}record;
int main()
{
    typedef record *p;//pointer declaration of struct type record
    p pointer;//pointer declartion
    pointer=(p) malloc (sizeof(record));//memory allocation to variable pointer
    pointer->a=10;//value assignment
    pointer->b=3.14;//value assignment
    pointer->c='a';//value assignment
    strcpy(pointer->city,"Kathmandu");//value being copied
    printf("i=%d \nf=%f\nc= %c\n",(*pointer).a,(*pointer).b,(*pointer).c);//value printing
    printf("the city=%s\n",pointer->city);
    free(pointer);
    return 0;

program to understand malloc() using struct

//understanding struct pointer
#include <stdio.h>
#include <stdlib.h>
struct reco
{
    int a;
    float b;
    char c;
};
int main()
{
    struct reco *p;//pointer declaration of struct type
    p=(struct reco *) malloc (sizeof(struct reco));//memory allocation
    p->a=10;//value assignment
    p->b=3.14;//value assignment
    p->c='a';//value assignment
    printf("i=%d \nf=%f\nc= %c\n",(*p).a,(*p).b,(*p).c);//value printing
    free(p);

}

to understand free() function

//understanding free()
#include <stdio.h>
#include <stdlib.h>

int main()
{
    int *x ;//pointer declaration
    x= (int*)malloc(10*sizeof(int));//allocates the memory for 10 integers(10x4=40)
                                    // to heap

    if(x==NULL)//tests whether the memory is available
    {
        printf("error in allocating");//displays error if no memory
    }
    else
    {
    printf("%d\n", sizeof(x));//prints value 4. Because the
                            //sizeof thinks what memory each value/integer will occupy
    }
    free(x);//frees the memory.
    return 0;
}

understanding malloc()

//understanding malloc()
#include <stdio.h>

{
    int *x ;//pointer declaration
