Consider the code snippet below: ifstream myFile; myFile.open("input.txt"); if(!myFile){ //First Block } else { //Second Block } If you were to compile and run this code and find that "First Block" executes, what is one possible explanation? was not included in the program. input.txt does not exist. input.txt is too large for the compiler to open. A filestream cannot be in a condition because it is not an integer.
