Use DEV C and VS 2019 compile the same code output is not the same!!-CodePudding

As title, code:
#include
#include
Int fn (int a, int n);//function declaration
Int main (void) {
Int a, n, sum;
int i;
Sum=0;
The scanf (" % d % d ", & amp; A, & amp; n);
//enter a, n
for(i=1; i<=n; I++) {
The sum +=fn (a, I);//loop accumulative
}
Printf (" Sum=% d ", Sum);
return 0;
}

Int fn (int a, int n)
{
Int result=0;
for(int i=0; i{
Result=result + a * pow (10, I);//pow says 2 of 3 (2, 3)
}
return result;
}

On the DEV c + + output is the Sum of=98756
In VS 2019 output is the Sum of=98760
I want the result is the Sum of=98760, but the school is DEV compiler,
Two compilers is where step processing lead to different results of different?
Beg big help!!!!!!!!!!

Results should be identified,
Is not the same as that of code has a problem, need to modify,,
You also don't say to complete what function, who also can't help you,,,

CodePudding user response:

Modified as follows, for your reference:

 # include 
#include 
Int fn (int a, int n);//function declaration 
Int main (int arg c, char * argv []) 
{
Int a, n, sum; 
int i; 
Sum=0; 
The scanf (" % d % d ", & amp; A, & amp; n);//enter a, n 

for(i=1; i<=n; I++) {
The sum +=fn (a, I);//loop accumulative 
} 
Printf (" Sum=% d ", Sum); 
system("pause"); 
return 0; 
} 

Int fn (int a, int n) 
{
Int result=0; 
for(int i=0; iThe result +=a * pow (10, I);//pow says 2 of 3 (2, 3) 
} 
return result; 
}

CodePudding user response:

This is the building in front of the code, it is correct, this is to modify, another kind of writing, for reference:

 # include 

Int fn (int a, int n);//function declaration 
Int main (int arg c, char * argv []) 
{
Int a, n, sum; 
int i; 
Sum=0; 
The scanf (" % d % d ", & amp; A, & amp; n);//enter a, n 

for(i=1; i<=n; I++) {
The sum +=fn (a, I);//loop accumulative 
} 
Printf (" Sum=% d \ n ", Sum); 

system("pause"); 
return 0; 
} 

Int fn (int a, int n) 
{
Int result=0; 
for(int i=0; i//result + (10, I)=a * pow.//pow says 2 of 3 (2, 3) 
Result=result * 10 + a; 
} 
return result; 
}

CodePudding user response:

Show a, only supplies the reference:

 # include & lt; stdio.h> 

Int fn (int a, int n) 
{
If (n==1) return a; 
The else return a * (10 * fn (1, n - 1) + n); 
} 

Int main (void) 
{
Int a, n. 
The scanf (" % d % d ", & amp; A, & amp; n); 
Printf (" Sum=% d ", fn (a, n)); 
return 0; 
}

The

reference 3 floor QZJHJXJ response:

modify as follows, for reference:

 # include 
#include 
Int fn (int a, int n);//function declaration 
Int main (int arg c, char * argv []) 
{
Int a, n, sum; 
int i; 
Sum=0; 
The scanf (" % d % d ", & amp; A, & amp; n);//enter a, n 

for(i=1; i<=n; I++) {
The sum +=fn (a, I);//loop accumulative 
} 
Printf (" Sum=% d ", Sum); 
system("pause"); 
return 0; 
} 

Int fn (int a, int n) 
{
Int result=0; 
for(int i=0; iThe result +=a * pow (10, I);//pow says 2 of 3 (2, 3) 
} 
return result; 
}

What is the meaning of the fourth row?

Bosses, how do you want to come out the recursive function?

Bosses, how do you think of the recursive function? O idea!
