Introduction Solution Don’t use special shell characters in your file names. & is special, so C&Cpp will bite you, again and again and again and again AND AGAIN AND AGAIN. Special shell characters in filenames are not illegal, and you…
Introduction Solution #include<iostream> using namespace std; void initarray(int a[], int n) { for(int i = 0; i<n; i++) { a[i]=0; } } void acceptarray(int a[], int n) { for(int i = 0; i<n; i++) { cin >> a[i]; } }…
Introduction Solution class MainClass { public static void Main (string[] args) { int counter = 1; do { for (int i = 0; i < counter; i++) { Console.Write(“*”); } Console.WriteLine(); // for newline counter++; // increase counter } while…
Introduction Array of arrays, or “nested arrays,” is a powerful concept in programming that allows for the storage of multiple sets of data in a single array. This concept can be used to store complex data structures, such as a…
Introduction C++ is a powerful programming language that allows developers to create complex applications. One of the most important aspects of C++ is its ability to compare different types of variables. However, it is important to note that C++ does…
Introduction The C#6 “Using static” feature is a great way to simplify your code and make it easier to read. It allows you to access static members of a type without having to specify the type name. This can be…
Introduction Validating phone and telephone numbers of Hong Kong with a country code using regular expressions (regex) can be a daunting task. However, with the right knowledge and understanding of regex, it can be done quickly and accurately. In this…
Because the expression num1++ evaluates to num1. You may want to do: ++num1 which evaluates to num1 + 1. Note however that both expressions increment num1 by one. Evaluating num1 in the next statement evalutes to the incremented value. In…
Introduction The ‘–>’ operator is a pointer operator in C It is used to access the members of a structure or union. It is also known as the structure dereference operator and is used to access the members of a…
–> is not an operator. It is in fact two separate operators, — and >. The conditional’s code decrements x, while returning x‘s original (not decremented) value, and then compares the original value with 0 using the > operator. To…
fopen, calloc, and realloc can all fail, returning NULL. In the case of realloc, the original allocation will remain untouched, so immediately overwriting the original pointer with the newly returned value will leak memory and throw away potentially useful data.…
Your code exhibits undefined behaviour because you passed a non-static, uninitialised pointer to realloc whose contents were indeterminate. From C11, Memory Management Functions: The realloc function deallocates the old object pointed to by ptr and returns a pointer to a…
When processing regular characters (final else clause) you read additional input instead of operating over text, i.e. instead of: scanf(“%c”, &document[parano][sentno][wordno][charno]); printf(“%c\n”, document[parano][sentno][wordno][charno]); charno++; you want to do: document[parano][sentno][wordno][charno++] = text[i]; By the time we hit text[i] == ‘ ‘…
Introduction If you’ve been struggling with a document for two days and can’t seem to get it to work, you’re not alone. Many people have difficulty understanding the complexities of document formatting and troubleshooting. Fortunately, there are many resources available…
You want to modify the value of an int* (your array) so need to pass a pointer to it into your increase function: void increase(int** data) { *data = realloc(*data, 5 * sizeof int); } Calling code would then look…
