Here is the solution . Please give a thumbs up!!
Memory leaks occur due to following reasons
1) char *aString = "Memory Leaks" , here the constant "Memory leaks" is declared in the heap memory and address is give to aString pointer and this memory is never released this is one of the potential memory leaks
2) The 2 dimention pointer strList is allocated memory on the heap but memory given to it is not realeased in the program
3) aString 1 dimension char pointer memory is never released this is one of the potential memory leaks
Q.25. Given the following program, you are asked to discuss memory leaks caused in its execution....
In the following code, what is the first line that introduces a memory leak into the program? (Type the line number into the box below) 1: #include <stdio.h> 2: #include <stdlib.h> 3: #include <string.h> 4: int main() { 5: char *word1 = NULL; 6: word1 = malloc(sizeof(char) * 11); 7: word1 = "bramble"; 8: char *word2 = NULL: 9: word2 = malloc(sizeof(char) * 11); 10: word2 = word1; 11: return 0; 12: }
C program help #include #include #include void PrintName(char firstname[16], char lastname[16]); int main () { char firstname[16]; char lastname[16]; printf("please enter your first name:"); scanf("%s",firstname); printf("please enter your last name:"); scanf("%s",lastname); PrintName(firstname,lastname); return 0; } void PrintName(char firstname[16], char lastname[16]){ char fullname[34]; *fullname=*firstname+*lastname; (char*) malloc (sizeof (*fullname)); if (strlen(firstname) > 16||strlen(lastname)>16||strlen(fullname)>16) fflush(stdin); else printf(" the full name is %s %s \n",firstname,lastname); printf(" the full name is-> %s",fullname);/*why is one not run*/ return 0; }
Given the following source programs, write down the letter that correspond to the right answer #include <stdio.h> #ifndef MEMORY #include "myhead.h" #include <stdlib.h> myhead.h #include <string.h> int main() { #endif char *text= MEM(SIZE, char); #define SIZE 10 COPY_TEXT (text, MSG); #define MSG "CS262" newtext (text); #define MEM(size, type) SHOW (text); (type *) malloc(size * sizeof(type)) free (text); #define COPY_TEXT (dest, source) return 0; strcpy (dest, source) } text.c #define SHOW (x) printf("Output: %s\n", x) void newtext (char *text) { int...
I'm having trouble getting my program to output What is your first name? damion what is your last name? anderson damion, Your first name is 6 characters Your last name, anderson, is 8 characters Your name in reverse is: noimad nosredna This is my code so far: #include <stdlib.h> #include <stdio.h> void sizeOfName(char** name); void printSizeOfName(int *first, int *last, char** name); void reverseString(int *first, int *last, char** name); int main() { char** name; name = (char**)malloc(2*sizeof(char*)); name[0] = (char*)malloc(100*sizeof(char)); name[1]...
In Programming language C - How would I convert my words char array into a string array so I can use the strcmp() function and alphabetically sort the words? #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ctype.h> int main(int argc, char*argv[]){ int i =0; int j =0; int count =0; int length = strlen(argv[1]); for(i =0; i < length; i++){ if(isalpha(argv[1][i]) == 0 ||isdigit(argv[1][i] != 0)){ count ++; } printf("%c",argv[1][i]); } char *strings; int wordNum =0; int charNum =0; strings...
Could someone please help me with this C language code I'm confused as to why i'm getting an error every time I run it on command line if some could please help me as soon as possible. #include <stdio.h> #include <stdlib.h> int main() { char *ptr_two = (char *)malloc(sizeof(char)*50); printf("%p\n", ptr_two); ptr_two = "A constant string in C"; printf("%p\n", ptr_two); printf("%s\n", ptr_two); free(ptr_two); return 0; }
Create a UNIX makefile for the following C program: //convert.c char toUpper(char c){ if(c>='a' && c<='z') return c-32; return c; } //converting sentance to upper void convertSentence(char *sentence){ int i=0; while(sentence[i]!='\0'){ //convert to upper for each character sentence[i] = toUpper(sentence[i]); i++; } } //converting all sentences into uppercase void convertAll(char **sentenceList, int numOfSentences){ int i=0; while(i<numOfSentences){ //calling convertsentence function to conver uppercase convertSentence(sentenceList[i]); i++; } } sentences.c #include<stdio.h> #include<stdlib.h> #include "convert.c" int main(){ //declaring character array char **mySentences; int noOfSentences;...
"Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Assume simonPattern and userPattern are always the same length. Ex: The following patterns yield a userScore of 4: simonPattern: RRGBRYYBGY userPattern: RRGBBRYBGY #include <stdio.h>...
1. Select all that are true for the following code. #include <stdio.h> #include <stdlib.h> void range(int start, int end, int *results) { int length = end - start; results = malloc(sizeof(int) * length); for (int i=start; i<end; i++) { *results = i; results++; } } void printArray(int *arr, int length) { for (int i=0; i<length; i++) { printf("%d ", arr[i]); } } int main() { int *x; int s = 2; int e = 11; range(s, e, x); printArray(x, e...
If void * is a pointer to void is a "generic" pointer type, and a void * can be converted to any other pointer type * without an explicit cast, why in the ,myarrcopy function the malloc is created like char and not like void? if we are going to work with different type of arrays? Here is de program: *This is a function that make a copy of any given array. * We then use this function make a...
