Question

I have this problem with C.

I have the following statement.

int *a;
a=malloc(100);

And I get the following error:

error: invalid conversion from ‘void*’ to ‘int*’ [-fpermissive]

Any hints on this ?

Answer 1

You are compiling your code as C++, in which the code you’ve used is not valid. For C though, it is valid and you should not add any cast.

Note, however, that the argument to malloc() is in chars, so “100” is a bit random. If you want 100 integers, do:

a = malloc(100 * sizeof *a);
