How do you concatenate strings in Excel?

Is string interpolation more efficient than concatenation?

String concatenation is a little faster for a very small number of arguments, but requires more memory. After 20+ arguments concat is better by time and memory.

Is string interpolation faster than string format?

The following is a simple code I have, with a bunch of “for loops” with 100,000 iterations for each test: And I was really surprised to see that interpolation is the slowest of all. String concat with '+' took: 2,090 milliseconds. String Builder took: 1 milliseconds.

C program to concatenate two strings without using strcat ()

In this tutorial, we will learn how to concatenate two strings without using strcat () function in C programming language. We will take the input from the user. User will enter both strings, our program will concatenate the strings and print out the result. To store the strings, we will use two arrays.

Explanation

Create two char array variables to store the strings. These variables are firstString and secondString. The size of these arrays are 100.
