Write a program, named sortlist, that reads three to four integers from the command line arguments and returns the sorted list of the integers on the standard output screen. You need to use strtok() function to convert a string to a long integer. For instance,

In C++:

void sortlist(char nums[],int charlent){    

   int Myarr[charlent];

const char s[4] = " ";  

char* tok;  

tok = strtok(nums, s);  

int i = 0;  

while (tok != 0) {  

 int y = atoi(tok);

 Myarr[i] = y;

 tok = strtok(0, s);  

 i++;

}  

int a;  

for (int i = 0; i < charlent; ++i) {

for (int j = i + 1; j < charlent; ++j) {

 if (Myarr[i] > Myarr[j]) {

 a =  Myarr[i];

 Myarr[i] = Myarr[j];

 Myarr[j] = a;

       }   }  }

for(int j = 0;j<charlent;j++){ printf(" %d",Myarr[j]); }  

}

Explanation:

This line defines the sortlist function. It receives chararray and its length as arguments

void sortlist(char nums[],int charlent){    

This declares an array

   int Myarr[len];

This declares a constant char s and also initializes it to space

const char s[4] = " ";  

This declares a token as a char pointer

char* tok;

This line gets the first token from the char

tok = strtok(nums, s);

This initializes variable i to 0

int i = 0;

The following while loop passes converts each token to integer and then passes the tokens to the array  

while (tok != 0) {  

 int y = atoi(tok); -> Convert token to integer

 Myarr[i] = y; -> Pass token to array

 tok = strtok(0, s); -> Read token

 i++;

}  

Next, is to sort the list.

int a;

This iterates through the list  

for (int i = 0; i < charlent; ++i) {

This iterates through every other elements of the list

for (int j = i + 1; j < charlent; ++j) {

This condition checks if the current element is greater than next element

 if (Myarr[i] > Myarr[j]) {

If true, swap both elements

 a =  Myarr[i];

 Myarr[i] = Myarr[j];

 Myarr[j] = a;

       }   }  }

The following iteration prints the sorted array

for(int j = 0;j<charlent;j++){ printf(" %d",Myarr[j]); }  

}
