 // find all the numbers in a string
 // using isdigit() , isspace() 
 // finds the "." as well.
 // seperates each number with a return
 // the bool stops needless line returns.
 #include <ctype.h>  // you need this for isdigit() and isspace()
 #include <stdbool.h> // needed for bool

int main(){
  
 	char str[30] = " 203.987 This a test 2094";
    bool space = true;
    int i = 0;
  
    while (i < sizeof(str))
    {
        if (isspace(str[i]) && space)
        {
            printf("\n");
            space = false;
        }
        if ("." == &str[i])
        {
            printf(".");
            space = true;
        }
        if (isdigit(str[i]))
