Question

general problems faced in scanf function......(plzzzzzz...answer in simple...)

Answer 1

scanf is a function that can be used for various number of variables.. it is defined as scanf(const char *,...), the first part is a string that gives the program to understand what data types you want to scanf for (in simple terms).The most basic data types are:

%s ->string
%d -> integer
%ld -> long integer
%llu -> long long unsigned integer
%d ->simple integer
%c -> character

and remeber when you pass a variable in the function you have to use the & sign because the scanf function scans for pointers, not variables.Not putting the & sign can cause a segmentation fault.
example: scanf("%d %d %d", &number1,&number2,&numbers3);
scans for 3 integers and saves the result in number1,number2 and number 3..
