Most c+ + compilers check whether indices are within the range determined by an array's declaration. true false

I'd say True

In C+ + syntax, it is correct to exceed the valid range of indices for an array. However, this can cause problems like errors on compilation and runtime. Use of Brackets [] in C+ + have a close relationship with arrays. They specify the size of arrays when they are declared. They also specify indices for concrete array elements when they are accessed.
