Question

Please answer the following question ASAP.

Note write the function and write a separate test case for it. Thanks!

in C lanzuage findCommand.c int findCommand const char cmdString, const char commands l Look for the given cmdString in commands and return its index. CmdString is null e commands is null cmdString is not in commands Return Value: 1 if either argument is null or if cmdstring is not found. Otherwise, return 0 Nest uwite a test findCommnd.c test cases fhat test帕e find on-and . c on thal eu wnte abeve. re pelous is a more informaon on the nchon that need o bevunten int findCommand const char * cmdString, wn ten R C const char* commands Finds the index of cmdString in commands, and returns it o man-s3 strncmp Error cases(return-1) o cmdString not in commands o cmdString is null o commands is null

Find_command.c

This file is the main implementation.

#include <stdio.h>

#include <string.h>

#include <test.h>

int i=0;

int findcommand(const char *cmdstring, const char *commands[]){

//printf("%s", cmdstring);

int count=0;

for(i=0;i<4;i++){

if(commands[i]== cmdstring){

printf("it exists\n");

count=count+1;

}

}

if(count==0){

printf("it doesn't exists");

}

}

int main(void) {

int len;

const char *command[]={"ping google.com","search","exit","entry"};

extern const char *cmdstring1;

extern const char *cmdstring2;

extern const char *cmdstring3;

extern const char *cmdstring4;

len=strlen(cmdstring1);

if(len > 0){

findcommand(cmdstring1,command);

}

else{

printf("search command is null\n");

}

len=strlen(cmdstring2);

if(len > 0){

findcommand(cmdstring2,command);

}

else{

printf("search command is null\n");

}

len=strlen(cmdstring3);

if(len > 0){

findcommand(cmdstring3,command);

}

else{

printf("search command is null\n");

}

len=strlen(cmdstring4);

if(len > 0){

findcommand(cmdstring4,command);

}

else{

printf("search command is null\n");

}

return 0;

}

test.h

In this .h file you will have all your test cases. The reason which I have made it as .h file because it can be accessed by find_command.c if the test.h is a .c file it cannot be accessed inside the find_command.c program file.

#include <stdio.h>

#include <string.h>

const char* cmdstring1="entry";

const char* cmdstring2="exit";

const char* cmdstring3="";

const char* cmdstring4="ping";
