COM CONCATENAR DUES CADENES EN C++

Aquesta secció tractarà la concatenació de dues o més cadenes en el llenguatge de programació C++. La concatenació de la cadena significa el grup de caràcters que combina dues cadenes més per retornar una cadena única concatenada. Mentre es concatenen les cadenes, la segona s'afegeix al final de la primera per fer-ne una única.

Per exemple, tenim dues cadenes, ' Java 'i' Punt T ', i volem concatenar per fer una única cadena com Java + Tpoint = JavaTpoint.

Parlem de les diferents maneres de concatenar la cadena donada en el llenguatge de programació C++.
