Fill the diagram to show the contents of memory after each line of the following

Question

Fill the diagram to show the contents of memory after each line of the following code: int v1[] = {10, 15}, v2 = 25; int *p1 = v1 + 1, *p2 = &p1; *p1-- = 60; v2 = *p1 + **p_2; Implement char *ExpandedString(char *s, char ch); which creates a new string by inserting the given character ch after each char in the given string s. If there is no memory, it returns NULL. For example, ExpandedString ("ABC", '-'); returns a new string as "A-B-C-" char *ExpandedString(char *s, char ch); {/* Assume standard libraries stdlib.h, stdio.h, string.h are included */

Explanation / Answer

HI, Please find my implementation.

Please let me know in case of any issue.

   Content   
   v1[0]   70
   v1[1]   60
   v2    140
   p1     1004
   p2       1012

   char *ExpandedString(char *s, char ch){

       // finding length of d
       int len = strlen(s);

       // allocating memory for new character array
       char *new_s = (char *)malloc(2*len*sizeof(char));

       if(new_s == NULL){
           printf("Error in creating memory ");
           return NULL;
       }

       int k = 0;
       int i= 0;

       while(i < len){
           new_s[k++] = s[i];
           new_s[k++] = ch;
           i++;
       }

       new_s[k] = '';

       return new_s;
   }
