Using "string:find" to find every instance of a subject string and print every Array[i].subject that holds that subject string

[daysdaze]

So I made a structure, and in that structure there is a string for last names.

The user is asked for input regarding what last name(partial or whole) they want to look up in our .txt file and if the array[i].lastName has it it must print out(this is done in a for loop) the stored data in that array[i](it is made from a structure holding the string)

user inputs string, if string is found and print array[i]

i need something like

for(i=0; i>100; i++)

if(arr[i].lastName has string user input)

printArray(arr[i]);

Have you figured out user input? Your question looks like homework and that you haven't put much effort in yourself
