what does the result do not make sense?

I have programmed a small program to find the cos of any number bur the result was all strange the cmd :

type the number 0.00

effincisy5

your cos =008C129E

Press any key to continue . . .

the code:

#include <iostream>
#include <vector>
#include <cmath>
using namespace std;

float cos67 (float l,float j)
{
    int k=0;
    float sum=0,i=1;
    while (k<=j)
    {
        sum +=i;
        i*=(-l*l/((2*l)*(2*l-1)));
        k+=1;
    }
    return sum;
}
int main(){
    float l,j;
    cout<<"type the number ";
    cin>>l;
    cout<<endl<<"effincisy" ;
    cin>>j;
    cout<<endl;
    cos67(l,j);
    cout<<"your cos ="<<cos67<<endl;
    return 0;
}

so why the result have letters on the number?

or what does it mean?

You are printing the address of the function and not the return value. Use:

cout<<"your cos ="<< cos67(l, j) <<endl;

Instead.

This:

 cout<<"your cos ="<<cos67<<endl;

is taking the address of the function and displaying it. You want the value the function returns:

 cout<<"your cos ="<< cos67(l,j) <<endl;
