Hi, can someone help me code this in c++ format and provide an explanation?

Read fileName and five strings from input. Open fileName as an output file. If the file fails to open, use cout to output fileName followed by ": error opening file.", and do not proceed to the code that writes to the file. Otherwise, for each string read, write "ZIP code " followed by the string to the opened file. End each output with a newline and close the file. Ex: If the input is postal.txt 7897063042515236830657666 , then postal.txt contains: ZIP code 78970 ZIP code 63042 ZIP code 51523 ZIP code 68306 ZIP code 57666
