Using “wc -l” There are several ways to count lines in a file. But one of the easiest and widely used way is to use “wc -l”. The wc utility displays the number of lines, words, and bytes contained in each input file, or standard input (if no file is specified) to the standard output. 1.
Use wc –lines command to count the number of lines. Use wc –word command to count the number of words. Print the both number of lines and the number of words using the echo command.
Program to Count the Number of Digitswhile loop is iterated until the test expression n! = 0 is evaluated to 0 (false). After the first iteration, the value of n will be 345 and the count is incremented to 1. After the second iteration, the value of n will be 34 and the count is incremented to 2.
How about this :-
std::ifstream inFile("file"); std::count(std::istreambuf_iterator<char>(inFile), std::istreambuf_iterator<char>(), '\n'); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
