Simple C language programming-CodePudding

Small white a computer, what all can't, you will make a great god can help me solve this problem? Or what is the recommended way to learn C language?

The first topic is divided into molecular denominator to see on the second question is a person to make a digital algorithm suggested that look at my blog

Question 1:
int n;
The scanf (" % d ", & amp; N);
Float factor=1.0;
Float data=https://bbs.csdn.net/topics/0.0;
For (count=1; The count & lt;=n; Count + +)
{
Factor data +=1 * * 1.0/count;
}
Printf (" data: % f \ n ", data);

Question 2: make the 5 digit character array processing, each character is one of the character array, will this character array can be inverted,

# include & lt; stdio.h>

Int main () 
{
int n; 
int i; 
Double data=https://bbs.csdn.net/topics/0; 
Printf (" \ n * * * * * * * * * * * * * * * * * * * * * * * * * \ n "); 
Printf (" please enter an odd number: "); 
The scanf (" % d ", & amp; N); 
If (n % 2!=0) 
{
for(i=1; i <=n; I + +) 
{
The data +=pow (1, I + 1) * 1/I; 
} 
Printf (" data: % f \ n ", data); 
} 
The else 
{
Printf (" please enter an odd number "); 
} 
Printf (" \ n * * * * * * * * * * * * * * * * * * * * * * * * * \ n "); 

Int a, [5]. 
for(i=0; i <5; I++) 
{
Printf (" please input the first number: % d ", I + 1); 
The scanf (" % d ", & amp; A [I]); 
} 
Printf (" you input array is: "); 
For (I=4; i>=0; I -) 
Printf (" % \ t - 6 d, "a [I]); 
Printf (" \ n * * * * * * * * * * * * * * * * * * * * * * * * * \ n "); 

}

refer to the second floor fox emperor response:

1:
int n;
The scanf (" % d ", & amp; N);

For (count=1; The count & lt;=n; Count + +)
{
Factor data +=1 * * 1.0/count;

Question 2: make the 5 digit character array processing, each number is the characters in a character array, will this character array can be inverted,

If the second sentence display an error when running??????

Ok, thank you
