Why when I type of 9, the program for 81 as a result, instead of 83, there is wrong, please!!!!!!!!!!!

CodePudding user response:

Int n redefinition, I an uninitialized, I in use I for as a temporary variable, sushu logic also have problems
Below is change good

 # include & lt; stdio.h> 

Int sushu (int a) 
{
int b; 
For (b=2; b {
If (a % b==0) 
return 0; 
} 
return a; 
} 
Int main () 
{
Int sum=0, n, I, TMP. 
Printf (" please enter a number "); 
Scanf_s (" % d ", & amp; n); 
For (I=3; I & lt;=n; I++) 
{
TMP=sushu (I); 
The sum +=TMP TMP *; 
} 
Printf (" 3 ~ is % d % d primes the sum of the squares of the \ n ", n, sum); 
}
