Understanding strcpy (), strcmp (), and strcat () in C String manipulation in C is made much simpler through the inclusion of strcpy() to copy strings, strcmp() to compare strings, and strcat() to concatenate strings together Each solves a specific string problem However, care must be taken to use them properly and handle potential errors
Difference between concatenation of strings using (str += s . . . This article shows the difference between the concatenation of the strings using the addition assignment operator (+=) and the addition (+) operator used with strings Concatenation is the process of joining end-to-end
String. join () vs other string concatenation operations String join relies on the class StringJoiner which itself relies on an internal StringBuilder to build the joined string So performance-wise it's much the same as using a StringBuilder and appending to it, or using a chain of + (which nowadays are converted to StringBuilder operations by the compiler)
