Get scanf to quit when it reads a newline?

Question

If I input 5 5 at the terminal, press enter, and press enter again, I want to exit out of the loop.

int readCoefficents(double complex *c){
             


        

Answer 1

Instead of

while(scanf("%f %f", &real, &img) == 2)

try

while(scanf("%f %f%*c", &real, &img) == 2)


scanf("%f%*c", &myfloat); // will read a float and all eventual characters after it
