Which operator do you use to concatenate character string in a string expression?
In this article, we will unveil the various ways of performing string concatenation in the C++ language. This method can be used for various purposes while programming. But in general, the concept is the same as combining two strings from different locations and placing them together. Show Techniques of String Concatenation in C++The following techniques can be taken into consideration while concatenating strings in C++:
1. C++ ‘+’ operator for String ConcatenationC++ The ‘+’ operator adds the two input strings and returns a new string that contains the concatenated string. Syntax:
Example:
Output:
2. C++ strcat() methodC++ has a built-in method to concatenate strings. The The strcat() function takes char array as input and then concatenates the input values passed to the function. Syntax:
Example 1:
In the above example, we have declared two char arrays mainly str1 and str2 of size 100 characters. Then, we have passed the char array str1 and str2 to the strcat() function to get the concatenated string as a result. Output:
Example 2:
In the above example, we accept string input values
from the user using the Output:
3. The append() Method for String Concatenation in C++C++ has another built-in method: append() to concatenate strings. The Syntax:
Example:
In the above example, we have passed str2 as a parameter to the append() function. Further, the append() functions add the contents of the string object str2 to the end of the contents of string object str1. Thus, serving the purpose of string concatenation. Output:
4. Using C++ for loopIn order to concatenate strings, we can use C++ for loops to serve the purpose without the need of any in-built function. Example:
In the above snippet of code, we have accepted two char array inputs mainly: x and y, respectively. Further, we have traversed through the string of x char array till the pointer variable p points to the index of the last character of x. Then, we traverse through the character input of char array y and concatenate each character of y to x. In the end, we add a Output:
ConclusionThus, in this article, we have understood the various techniques to concatenate strings in the C++ language. References
Which operator is used to concatenate strings?The & character is used to concatenate, or join, two or more strings or the contents of referenced cells. Some examples of the use of the concatenation operator are: "Abc"&"Def" returns "AbcDef".
Which operator is used for string concatenation in Python?We can perform string concatenation using following ways: Using + operator. Using join() method.
