what is the functionality of auto keyword as used in this vector introduction video??

hello @mahfoozhaque91

the auto keyword is used in place of the datatype to tell the compiler to infer the variable’s type on its own.
it deduces the datatype on its own , we dont have to explicitly mention the tyep.

for example->

for(int i : vectorName) { //here int is the dataype
something 
} 
we can write the same thing with the help of auto without explicitly mentioning the datatype
 
for(auto i : vectorName) { //repalced int with auto 
something 
}
