Given the availability of an ifstream object named indata and an ofstream object named outdata, write the other statements necessary to read one integer from a file called currentsales and write twice its value into a file called projectedsales. Assume that this is the extent of the input and output that this program will do.
LANGUAGE: C++
CHALLENGE:
Given the availability of an ifstream object named indata and an ofstream object named outdata, write the other statements necessary to read one integer from a file called currentsales and write twice its value into a file called projectedsales. Assume that this is the extent of the input and output that this program will do.
SOLUTION:
double sales=0.0;
indata.open("currentsales");
outdata.open(""projectedsales"");
indata >> sales;
outdata << sales * 2.0;
indata.close();
outdata.close();
