The analyzer detected a possible error that has to do with accessing an element of an array or container by the same constant index at each iteration of a 'for' loop.
Consider the following example:
void Foo(vector<size_t> &vect)
{
for (size_t i = 0; i < vect.size(); i++)
vect[0] *= 2;
}The programmer intended this function to change all the values in a vector but made a typo that causes the vector elements to be accessed using the constant value 0 instead of the loop counter 'i'. It will result in changing only one value (unless the vector is empty).
To fix this error, we need to rewrite the line where the container's elements are accessed:
void Foo(vector<size_t> &vect)
{
for (size_t i = 0; i < vect.size(); i++)
vect[i] *= 2;
}You can look at examples of errors detected by the V767 diagnostic. |
