The 11th blue bowl individual campus E problem a method-CodePudding

E: a positive integer if any digital not greater than the right adjacent, is called a digital increasing number, such as the number 1135 is a digital incremental, and not a digital incremental number 1024,
Given a positive integer n, could you tell me in how many of the integers 1 to n a digital incremental number?
The original poster is a novice, here is the method of solution for this problem is
# include
# include
Int bj (int n);
Int main ()
{
Int x, c=0, t;
The scanf (" % d ", & amp; X);
For (t=1; T<=x; T++)
{if (bj (t)==1)
C + +;
}
Printf (" % d ", c);

}
Int bj (int n)
{
Int I=0, j, flag=1;
Int a, [6].
While (1)
{if (n>=10)
A [I]=n % 10;
The else
{a [I]=n;
break;
}
N=n/10;
i++;
}
for(j=0; J<=I; J++)
{if (a [j] flag=0;
}
Return flag;

}

May be a bit messy, way of thinking is to define an array, a function, use an array to n each store, and then from bits to compare with the number one by one on the left,

I run the feel no problem, please see if there is a more simple method

Reference:

 # include 
Bool bj (int n); 

Int main (int arg c, char * argv []) 
{
Int x, c=0, t; 
The scanf (" % d ", & amp; X); 
For (t=1; T<=x; T++) 
If (bj (t)) c + +; 
Printf (" % d ", c); 

return 0; 
} 


Bool bj (int n) 
{
Int j, k; 
K=n % 10; 
While (n) {
M=n % 10; 
If (m> K) return false. 
K=m; 
N/a=10; 
} 
return true; 
}

Judging function and then a brief step:

 bool bj (int n) 
{
Int j, k=n % 10; 
While (n=10)/{
M=n % 10; 
If (m> K) return false. 
K=m; 
} 
return true; 
}

Thank you bosses give directions, but why I generate solutions to make a mistake, I am using vc + + 2010, bool is what kind, I have never seen a

CodePudding user response:

Vc in the BOOL type, you try to BOOL, false in the function body into a false, true to true,
1, different types of
Custom types: BOOL type int, Microsoft typedef int BOOL;
Bool for Boolean, for c + + standard data type
2, different length
Bool is only one byte
BOOL length to be decided according to actual conditions, can generally be considered 4 bytes, because it is itself an int type
3, different values
Boolean value of false and true, and it is the difference between 0 and 1
Boolean value of FALSE and TRUE, and it is the difference between zero and non-zero
If several columns bool objects together, may each have a bit, depending on the compiler,
BOOL is defined by Microsoft typedef int BOOL) (in windef. J h, unlike BOOL, three value logic, it is a TRUE/FALSE/ERROR,

Thank you, the few compiler recognition not to come out, after changing capital should not be the problem, here is the code images and generate an error

The first change to BOOL:

 # include 

BOOL bj (int n); 

Int main (int arg c, char * argv []) 
{
Int x, c=0, t; 
The scanf (" % d ", & amp; X); 
For (t=1; T<=x; T++) 
If (bj (t)) c + +; 
Printf (" % d ", c); 

return 0; 
} 


BOOL bj (int n) 
{
Int j, k=n % 10; 
While (n=10)/{
M=n % 10; 
If (m> K) return FALSE. 
K=m; 
} 
return TRUE; 
}

The second change to int type:

 # include 

Int bj (int n); 

Int main (int arg c, char * argv []) 
{
Int x, c=0, t; 
The scanf (" % d ", & amp; X); 
For (t=1; T<=x; T++) 
If (bj (t)) c + +; 
Printf (" % d ", c); 

return 0; 
} 


Int bj (int n) 
{
Int j, k=n % 10; 
While (n=10)/{
M=n % 10; 
If (m> K) return 0; 
K=m; 
} 
return 1; 
}

Line 2, line 15 suggest there is a grammar mistakes, check under '; "What is the Angle or half Angle,
