Modify the int del_substr(char* str, char* substr) function, this function will take two string as parameter and check if the first string contains the second string as a sub-string, if the second string is a sub-string of first one return 1 and remove the sub-string from the first string. If it is not a sub- string, return 0 For example: if first string is "ABCD" and second string is "BC" therefore the function will return 1 and changes the first string to "AD" 3.
