Given the availability of an ifstream object named input wri

Given the availability of an ifstream object  named  input, write the other statements necessary to read an integer into a variable  datum that has already been declared from a file called rawdata. Assume that reading that one integer is the only operation you will carry out with this file. (Note: write just the statements , do not define a main function.)

Solution

Please let me know still you need more Information:-

========CODE STARTS=============

ifstream input; //declaration

int datum; //declaration

inupt = ... //open file rawdata

....... etc

while(input>>datum);//Here the integer value will be read to datum from filesream input

=========CODE ENDS======================

Now while to read a number from input of type ifstream you just need to read line by line if many values are there in file other wise you can read into one variable.

Thanks
