Returning memory from a function

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

char *get_street_address(void); /*function prototype*/

int main(void) {

char *street_address =  NULL;

street_address =  get_street_address();

/*Check if the above state is successful if not the program is terminated*/
assert(street_address != NULL):

printf("The entered street address was: %s \n",  street_address);

/*Return the memory block to the pool*/
free(street_address);

return 0;
}

/*Implement the function get_street_address(void)*/
char *get_street_address(void) {

/*Assign a memory of 150 characters to the "input" pointer*/
char *user_input = malloc(150);

/*Check if the memory assignment is successful*/
if (user_input == NULL) {
   printf("Unable to assign memory!\n");
   return NULL;
}

/*Ask for user_input*/
printf("Enter your street address: ");
scanf("%149s", user_input);

getchar();

return user_input;
}

Preventing memory leaks

char *b;
b=malloc(100);
free(b);

MATLAB GUI Edit Text and Static Text Objects Example

%Assume there is text_edit object which is called editext1.
%Assume there is a static_text object which is called statext1.

%Get the string in the text_edit object and convert it into a number n
n=str2num(get(handles.editext1,'string'));

%Do some thing with n
y=n*n;

%Convert y back into a string stry
stry=num2str(y);

%Set the 'string' field of the static_text object the string stry.
set(handles.statext1,'string',stry);

Image processing with MATLAB

1. Find and tracking a green ball from images/frames in a video in a MATLAB demo.
2. Creating a GUI with GUIDE
3. Open and display an image file in the GUI
4. Save a current image
5. MATLAB GUI for changing image brightness
6. MATLAB GUI for measuring image quality using PSNR and RMSE metrics

filename = uigetfile('*.jpg','Select an image file');
im = imread(filename);
imagesc(im);
%Create a handle to manage the image im
handles.im = im;
%Update handles structure/Save the change made to the structure
guidata(hObject, handles);

%Get the image im for manipulation
im = handles.im;
%Save the image im
[filename,pathname] = uiputfile( ...
       {'*.jpg', 'JPEG Image File'; ...
        '*.*',   'All Files (*.*)'}, ...
        'Save current image as');    
if (filename~=0)
        var=strcat(pathname,filename);
        imwrite(im,var);
end
