Doubt on push_back

#1

does push_back only take string-dataype arguments ?

#2

hello @prerak_semwal

no it depends on datatype of container.
for example->
a) vector v;
here datatype is string so we can push string. if it is of some other type then u can push data of that datatype.

ok…so is push_back defined in iostream header ?

#4

…

push back is memory function of string , vector ,deque class etc
its not in iostream

#5

@aman212yadav
ok…
here I used push_back for char datatype then why its not working

#6

u have defined char array , it does not have push_back function.

use c++ string, if u want to use push_back
