Question

Write a C++ program that will read in image data from the file "image.txt" and illustrate that image as ASCII art. The Image file will contain several lines, representing horizontal rows in the image, and each line will have several integers in the range 0-255. representing povels, separated by spaces. You should read this image data into a vector vector in Once you've read in the phel data, go through the image and print out each piel in the image as an ASCII character according to the chart below. Min Character walue space 104 119 135 150 175 134 149 174 255 is For example, apie value between 135 and 149 should be printed as a zero. The backtick character() is left of the 1 on most keyboards, and tilde (-) is shift. The pipe character shiftbackslash Your program should print its output to the console and to the file "output.txt". Don't forget to print a newline character at the end of each row of the image.

#include <vector>

#include <sstream>

   //Reading the file into the vector
   while (std::getline(fin,row))
