Using a loop for string concatenation: Using a loop is another way to combine the string values of the char array. Create a C++ file with the following code to check the use of the ‘for’ loop for combining the string values stored in two char array variables. Two string variables and...

//Performing Concatenation of two strings using the + operator in CPP s3 = s1 + s2; cout << "\n\nThe resulting string after the Concatenation of the two strings is :\n\n"; cout << "String3 = String1 + String2\n"; cout << "String3 = " << s3 << " and its lenght is " ...
You are given a string, s, and a list of words, words, that are all of the same length. Find all starting indices of substring(s) in s that is a concatenation o...
char*strOne ="Test string"; ... a terminating null character is automatically added to the end of the string, but when you allocate it like this: charstrTwo[50]; ... no terminating null character is appended. strcat() would look for the first '\0' in this string, and it could be...

It would be cleaner not to have to give each command name twice, once in the string constant and once in the function name. A macro which takes the name of a command as an argument can make this unnecessary. The string constant can be created with stringification, and the function name ...
