This needs to b written in C language:

#include

#define OPTIONS1 "./program name, option, num1, num2"

void dispErr(char* , char*);

void prnArgs(FILE*, int, char *[]);

/*This current version uses OPTIONS1 defined above for the format of command line argument*/

/* modify your code so that you can do the followings: */

/* Option =2 */

/*void Highest( your argument); to use float numbers from command line to get the highest number*/

/* Option =1 */

/*void Avg( your argument); to use float numbers from command line to get float average*/

int main( int argc, char *argv[] ) {

3. Do the following modifications: 1] write a function Highest (which is already outline inside the code) will take arguments like void prnArgs(FILE* fpL7, int argc, char *argvll) then: finds highest number for except first two arguments print to console print to file 2] write a function Avg (which is already outline inside the code) will take arguments like void prnArgs(FILE* fpL7, int argc, char *argv[I) then: find avg of arguments except first two print to console print to file 3. Do the following modifications: 1] write a function Highest (which is already outline inside the code) will take arguments like void prnArgs(FILE* fpL7, int argc, char *argvll) then: finds highest number for except first two arguments print to console print to file 2] write a function Avg (which is already outline inside the code) will take arguments like void prnArgs(FILE* fpL7, int argc, char *argv[I) then: find avg of arguments except first two print to console print to file
