COMO CONCATENAR DUAS STRINGS EM C++

Esta seção discutirá a concatenação de duas ou mais strings na linguagem de programação C++. A concatenação da string significa o grupo de caracteres que combina mais duas strings para retornar uma única string concatenada. Ao concatenar as strings, a segunda string é adicionada no final da primeira string para formar uma única string.

Por exemplo, temos duas strings, ' Java ' e ' Ponto T ', e queremos concatenar para formar uma única string como Java + Tpoint = JavaTpoint.

Vamos discutir as diferentes maneiras de concatenar a string fornecida na linguagem de programação C++.

Concatenar duas strings usando loop for
Concatenar duas strings usando loop while
Concatene duas strings usando o operador +
Concatene duas strings usando a função strcat()
Concatene duas strings usando a função append()
Concatenar duas strings usando herança
Concatene duas strings usando a função Friend e a função strcat()

Programa para concatenar duas strings usando o método strcat()

Função strcat(): O strcat é uma função embutida da classe string, que adiciona duas strings de caracteres para retornar uma string concatenada.

Sintaxe

 strcat ( char *arr1, char *arr2)

Existem duas matrizes de caracteres na sintaxe acima, arr1 e arr2, que são passadas dentro da função strcat() para retornar uma string concatenada.

Vamos considerar um exemplo para combinar duas strings usando a função strcat() na programação C++.

Programa para concatenar duas strings usando a função anexar

função anexar(): Um acrescentar() function é uma função de biblioteca predefinida usada para inserir ou adicionar uma segunda string no final da primeira string para retornar uma única string.

Sintaxe

 str1.append(str2);

Na sintaxe acima, str2 é uma segunda string a ser passada na função append() que insere a string str2 no final da string str1.

Vamos considerar um exemplo para combinar duas strings usando a função append() na programação C++.

Programa5.cpp

 #include using namespace std; int main () { string str1, str2, result; // declare string variables cout &lt;&gt; str1; // take string cout &lt;&gt; str2; // take second string // use append() function to insert element at the end of the str1 str1.append(str2); cout &lt;&lt; &apos; 
 The concatenation of the string is: &apos;&lt;&lt; str1; return 0; }
