You can not compare a char string with an element enclosed in single quotes, that is

menu == 'deposito' // deveria ser:
menu == "deposito"

Here is your complete code, I changed the printf to elements of the iostream library since you said the code is c ++ and they are easier to use and understand.

#include <iostream>

std::string nome, menu;
float saldo, valor;

main()
{
    std::cout << "Digite seu nome: \n";
    std::cin >> nome;
    std::cout << "Digite o saldo: \n";
    std::cin >> saldo;
    std::cout << "Digite o valor: \n";
    std::cin >> valor;

    std::cout << "Digite uma das opcoes (saldo/deposito/retirada):\n";
    std::cin >> menu;

    if (menu == 'deposito') {
        saldo = saldo + valor;
        printf("O saldo mais o valor depositado e igual a: %.2f\n", saldo);
    }
    else if (menu == 'retirada') {
        saldo = saldo - valor;
        printf("O saldo menos o valor depositado e igual a: %.2f\n", saldo);
    }
    else if (menu == 'saldo') {
        printf("O saldo e igual a: %.2f\n", saldo);
    }
    else {
        printf("Erro");
    }
}
