error -1.#IND00 in vc++2010

[yahya77]

hello; I tried to write a function that calculates the harmonic average as follows:

long double Harmonique(long double *t,int l)
{
long double s=0.0;
for(int i=0;i

the console I have this error -1.#IND00 .
what is the origin of this error ?

what are the values of 'l' and 's', when you hit this line:

return l/s;

I think you should check address of pointer and length of array

[Thong LeTrung]

I have checked on visual studio 2010 , you can check again

#include
#include
using namespace std;

long double Harmonique(long double *t,int l)
{
long double s=0.0;
for(int i=0; i

I am sorry , I see error for you . I have a example , i hope this example will help you. What will be output of the following program?

#include
int main(){
float a=0.7;d
if(a<0.7){
printf("C");
}
else{
printf("C++");
}
return 0;
}

EXPLANATION Output: Turbo C++ 3.0: c Turbo C ++4.5: c Linux GCC: c Visual C++: c Explanation: 0.7 is double constant (Default). Its binary value is written in 64 bit. Binary value of 0.7 = (0.1011 0011 0011 0011 0011 0011 0011 0011 0011 0011 0011 ) Now here variable a is a floating point variable while 0.7 is double constant. So variable a will contain only 32 bit value i.e. a = 0.1011 0011 0011 0011 0011 0011 0011 0011 while 0.7 = 0.1011 0011 0011 0011 0011 0011 0011 0011 0011 0011 0011.... It is obvious a < 0.7

Here, I found the solution. the * t I used in "main" was of type int, so there was a problem of division by zero. thank you for example and help.

now it's clear. thinks
