Question

C-programming

In activity 1, a function will accept an input string composed of a command and a parameter. The function will extract the command and convert the parameter into an integer. The conversion of the string to an integer can be done using atoi()- alphanumeric to integer. stdlib.h needs to be included. Note that the parameter characters, e.g., “10”, need to be extracted from the input string, assign to an array, and fed to atoi().

Write a function that accepts an input command and extracts the command and its parameter. Based on the prototype below, cmd and params variables will have the command and parameter, respectively. Display command and parameter in the main function.

Input: Move 100

    Command: Move

    Parameter: 100

#include

void my_func(char *str1,char *cmd, int *params)

void main(void){

char str[20]={};

char command[10] = {};

int parameter;

printf("Enter command and parameters :");

gets(str);

my_func(str, command, ¶meter);

} //End main

void my_func(char *str1,char *cmd, int *params) {

} //End my_func

If you have any doubts, please give me comment...

#include <stdio.h>

#include <stdlib.h>

#include<string.h>

void my_func(char *str1, char *cmd, int *params);

void main(void)

{

char str[20] = {};

char command[10] = {};

int parameter;

printf("Enter command and parameters :");

gets(str);

my_func(str, command, &parameter);

printf("Command: %s\nParameter: %d\n", command, parameter);

} //End main

void my_func(char *str1, char *cmd, int *params)

{

char *token = strtok(str1, " ");

strcpy(cmd, token);

*params = atoi(strtok(NULL, " "));

} //End my_func
