Consult the C language subject, thank you!-CodePudding

1 fill in the a, b

#include
Float calc_bmi (float height, float weight) {
Float bmi;
(a) (calculate bmi)
Return (bmi);
}
Int main (void) {
Float height, weight, bmi;
Printf (" height ");
The scanf (" % f, & amp; Height);
Printf (" weight ");
The scanf (" % f ", & amp; Weight);
(b) (BMI) was calculated by the function calc_bmi;
Printf (" BMI is % f ", BMI);
}

PI=4 * (1-1/3 + + 1/9-1/5-1/7 1/11 +... + (1) ^ n - 1/(2 n - 1)
N=1000, write approximately equal to PI program

Thank you very much!

CodePudding user response:

The first topic, BMI is: weight/height ^ 2, know this subject can write, do you
The second question: write a recursive with respect to OK, pass n to recursive function, the return value x 4

CodePudding user response:

1, (a) statement: bmi=height/weight; What bmi representative here, I am assuming that is divided by the weight, height
(b) statement: bmi=calc_bmi (height, weight);
The scanf (" % f, & amp; Height); Inside the parentheses "less % f", the correct is: the scanf (" % f ", & amp; Height);

Second question of the algorithm, and should be more accurate:

While (n

++n; 
PI=PI + t; 
S=-s; 
T=s/(2 * n - 1); 
} 
PI=PI * 4; 
Printf (" PI=% f \ n ", PI); 
//cin> s; 
return 0;

2 topic algorithm, change, should be more accurate:

 # include & lt; stdio.h> 
#include  
#include

Int main (int arg c, char * argv []) 
{
Int s=1; 
Float n=1, t=1, PI=0; 
While (n
=1000){
++n; 
PI=PI + t; 
S=-s; 
T=s/(2 * n - 1); 
} 
PI=PI * 4; 
Printf (" PI=% f \ n ", PI); 
//cin> s; 
return 0; 
}

thank you very much! trouble
