Reading a file and print the content in C

Question

I'm learning how to write and read files in C, and I wrote a text using this code

 FILE *f = fopen("testingText.txt", "w");
 char *text = "This is text1...";
 fwrite(text, sizeof(char), strlen(text), f );
 fclose(f);

and when I read the content of this file and print it using this code

 FILE *f = fopen("testingText.txt", "r");
 fseek(f, 0, SEEK_END);
 unsigned int size = ftell(f);
 fseek(f , 0, SEEK_SET);
 char *content = (char *)malloc(size);

 fread(content, sizeof(char), size, f);
 printf("File content is...\n%s", content);


 free(content);
 fclose(f);

it gives the result with strange things like these

File content is... This is text1...Path=C:*┬#æ╩eò*

and when I run the code again it gives different strange things.

There is no null terminator in the file so you'll need to add that manually before printing what you've read from the file.

Example:

char *content = malloc(size + 1);               // +1 for the null terminator
size_t chars_read = fread(content, 1, size, f); // store the returned value
content[chars_read] = '\0';                     // add null terminator
printf("File content is...\n%s\n", content);    // now ok to print
