c++ - Populating a vector with random numbers -
i'll dive right in: given piece of code professor that's supposed generate random numbers , compiler (g++) keeps throwing these errors: "warning: pointer function used in arithmetic [-wpointer-arith] rand[i]=((double) rand() / (static_cast(rand_max) + 1.0))* (high - low) + low;" "error: invalid cast type 'std::vector' type 'double' rand[i]=((double) rand() / (static_cast(rand_max) + 1.0))* (high - low) + low;" both point function generates random numbers. trouble i've used exact same function before , worked fine. have no idea wrong. appreciated. note still new c++. i've included: cstdlib, stdio.h, cstdio, time.h, vector, iomanip, fstream, iostream, cmath. code have now: int main() { int n=20000; std::srand((unsigned)time(0)); for(int = 0; i<(n+1); ++i) { double high = 1.0, low = 0.0; rand[i]=((double) rand()/(static_cast<double>(rand_max) + 1.0))*(high - low) + low; } return 0; } you using nam...
