Pray god help to look at the code where the error, thank you very much-CodePudding

Beginners can not see where there is a problem, not an error, you can perform,
Would like to ask the average has been=0,
#include

Float business (float sum [10]);

Void main ()
{
Float score [10], the result;

Printf (" please enter the number 10: \ n ");

The scanf (" % d ", & amp; Score);

Result=average (score);

Printf (" business=% f ", result);

}
Float business (float sum [10])
{

Float resule=0, I;

for(i=0; i<10; I++)
{
Resule +=sum [10].

}
Resule/=10;

Return the resule;
}

CodePudding user response:

The building Lord did not make clear the scanf usage, if you want to input 10 value to use a loop to input, this will only get a value, the array a [] in the scanf don't add & amp;
Is address values, then the function part, resule +=sum [10]. This is not a 10, but, every time you add is an array of all 9, is zero. So you output is 0

#include

Float business (float sum [10]);

Void main ()
{
Float score [10], the result;

Printf (" please enter the number 10: \ n ");

for (int i=0; I & lt; 10; I++)
{
The scanf (" % f ", & amp; Score [I]);
}

Result=average (score);

Printf (" business=% f ", result);

}
Float business (float sum [10])
{

Float resule=0;

for (int i=0; I & lt; 10; I++)
{
Resule +=sum [I];
}
Resule/=10;

Return the resule;
}

The building Lord help you to change good, not
the upstairs.

Ok thank you very much,

CodePudding user response:

refer to the second floor flowers blowing in the wind flowers response:

# include & lt; Stdio. H>

Float business (float sum [10]);

Void main ()
{
Float score [10], the result;

Printf (" please enter the number 10: \ n ");

for (int i=0; I & lt; 10; I++)
{
The scanf (" % f ", & amp; Score [I]);
}

Result=average (score);

Printf (" business=% f ", result);

}
Float business (float sum [10])
{

Float resule=0;

for (int i=0; I & lt; 10; I++)
{
Resule +=sum [I];
}
Resule/=10;

Return the resule;
}

The building Lord help you to change good, don't believe the upstairs,

The upstairs also will be a problem

Still need to have a good learn ~ for array
