"Create a program that calculates the inner product of a vector, and the data is input from the keyboard."


I tried to do this but I got an error saying that it expects 'float' because there is 'double'.Perhaps you can help me out?



#include <stdio.h>
double main()
{
int i;
double a,b,c,x,y,z;
double ip = 0.0;
double u[] = {a,b,c};
double v[] = {x,y,z};
printf("enter vector here\n");
scanf("%f,%f,%f,%f,%f,%f",&a,&b,&c,&x,&y,&z);
for (i = 0;i < 3;i++)
{
ip = ip + u[i] * v[i];
}
printf("innerproduct%f\n",ip);
return 0;
}

%lf is what you should use with doubles, not %f.
