Given input file(input.c):
/*Sum of Natural Numbers
using for loop*/
#include <stdio.h>
int main () {
int n, i, sum = 0;
printf("Enter a positive integer: ");
scanf("%d", &n);
//loop starts here
for (i = 1; i <= n; ++i) {
sum += i;
}
printf("Sum = %d", sum);
return 0;
}
1. Implement a Lex program to copy the content of input file (input.c) to another file (input_copied.c) and remove single-line comments, multi-line comments and whitespaces in input_copied.c file.
2. Implement a Lex program to print the count and line number of identifiers, keywords and operators in input_copied.c file.
Upload your code with its output in .zip or .rar.
