I'd like to know how to add multiple results. I'm creating a simple application for a particular financial challenge. For example:
double salario = 1500;
double desafio;
for(double mes=1; mes<=12; mes++){
desafio = (salario * mes)/100;
System.out.println("Valor do Desafio:" + desafio);
}
This code generates as a result all the monthly values that need to be "deposited", perfect. I wanted to know how I can add all these generated results.
Would that be?
double salario = 1500;
double desafio = 0;
for(double mes=1; mes<=12; mes++){
desafio += (salario * mes)/100;
System.out.println("Valor do Desafio:" + desafio);
}
This will sum the previous values with the current one. See working at ideone: link
If you want to continue displaying the values for each month, simply create a temporary variable inside the loop:
double salario = 1500;
double desafio = 0;
for(double mes=1; mes<=12; mes++){
double mesAtual = (salario * mes)/100;
desafio += mesAtual;
System.out.println("Valor do Mes Atual:" + mesAtual);
}
System.out.println("Valor do desafio:" + desafio);
The output will be:
Valor do Mes Atual:15.0
Valor do Mes Atual:30.0
Valor do Mes Atual:45.0
Valor do Mes Atual:60.0
Valor do Mes Atual:75.0
Valor do Mes Atual:90.0
Valor do Mes Atual:105.0
Valor do Mes Atual:120.0
Valor do Mes Atual:135.0
Valor do Mes Atual:150.0
Valor do Mes Atual:165.0
Valor do Mes Atual:180.0
Valor do desafio:1170.0

Declare and initialize a variable to receive the total:
double total = 0;
To sum the values use the following command (inside the loop):
total += desafio;
pretty much equals total = total + desafio;
