why auto is used in the for loop? Can we solve it without using auto??

hello ambuj,
auto detects datatype automatically .

if u dont to use auto keyword then u need to define datatype explicitly.

for example if u want to iterate on string using iterator
then using auto u can do something
for(auto it = s.begin() ; it != s.end() ; it++)

without using auto
for( string::iterator it = s.begin(); it != s.end() ; it++)
