This function contains two parameters. Find the starting indices of substrings in a character vector. Step3: The second loop (i.e. j can be incremented. The only difference between the two functions is the parameter. In general, a string is an immutable object, meaning that its value cannot be modified. We can use Python list comprehension to check if the array contains substring or not. The length of the character array includes the terminating '\0' character (and any chars in the array beyond that, although the way you've initialized the arrays precludes that). Open Live Script. In the following program, we take a string in str and substring in substr, take a for loop to iterate over the indices of string str, check if substring is present from this index.
