The contents of this string are modified and broken into smaller strings tokens. The strcmp compares two strings character by character if the first character of two strings is equal, the next character of two strings are compared. Bubble sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order. Number of writes is on 2 on average, but number of comparisons may vary depending on the insertion algorithm. Selection sort works by first starting at the beginning array index 0 and traverses the entire array comparing each value with the current index, if it is smaller than the current index than that index is saved. There are three expressions separated by the semicolons. Mastering algorithms with c offers you a unique combination of theoretical background and working code.
