Reading and Writing Text Files

COM1100 -- Winter2000 -- Yuhong Yin

Question 4 -- solution

• ifstream inFile; // declare an input file stream

ofstream outFile; // declare an output file stream

GetInputFile(inFile); // call GetInputFile (See slide 4)

GetOutputFile(outFile); // call GetOutputFile (See slide 5)

char ch; // declare a char variable

while ( inFile.peek() != EOF ) { // test if at the End Of File

inFile.get(ch); // read one character a time from input file

if ( ch == ` `)

outFile.put(`*`); // replace the blank with a star

else

outFile.put(ch); // write(copy) the character to output file

}

inFile.close(); // close the input file stream

outFile.close(); // close the output file stream
