To solve this program, a two-dimensional string str is created.
This string can hold maximum of 10 strings and each string can have maximum of 50 characters (including null character).
To compare two strings, strcmp() function is used. Also, we used strcpy() function to copy string to a temporary string temp.
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
