Does the char array contain a string?

Question

I have a text file and I want to check if it contains a string. The text file is stored in a char: array char buffer[512][128];.

Q1: Is it easier to buffer it in one long array instead of a multidimensional array? Q2: How can I check if the buffer contains a string char *s1 = "Hello world!";? I will need to search for a few lines.

Answer 1

• It will be much easier for us to use a single 1D array.

• strstr(buffer, s1)! = null (as soon as you change bufferto a 1D array)

Answer 2

strstr
