I think the issue was by ths following ,
Why do we pass exp[i]- '0' in the push if exp[i] is a digit but don't do the same in case of operator

Postfix Evaluation in C

hop of those help? If i try to run your program with 2 + 3, I'm gonna get underflow.
The 2 is going to get pushed onto your stack:
if(isdigit(eval)){
    push((eval-'0'), &infix_stack);
    showStack(&infix_stack);
}
opr2 = pop(&infix_stack);
opr1 = pop(&infix_stack);

Does type conversion happen if assigning a number to a long type without postfix "L"

wish of those help Yes, it involves conversion. But with a literal like this, the conversion will normally happen at compile time, so appending the L won't make any real difference unless you find the code more readable with the L there (I normally don't).
There are a few cases where you can append a suffix to get a result that's actually different from what you'd get without the suffix, but the ones you've shown don't fall into this category.

Postfix evaluation 3

will help you i have worked for this question couple of days and im at the end. Code works well for the input numbers between 0 and 9. but when input is more than 9 for example 28 72 * 13 + 20 67 * + it doesn't print correct answer. I don't know what to implement in order to code work. I cant change main function. I can change only inside of static int evaluatePostfix(char [] izraz, int n) , Instead of Character, try String like below:
Replace this code:
    ArrayStack<Character> e = new ArrayStack(n);
    char ch=0,res=0,a,b;
    int op1,op2,result=0,c=0;
    int z;
    for(int i=0; i<n; i++)
    {
       if(Character.isDigit(izraz[i]))
       {

          ch=izraz[i];

          e.push(ch);  


       }
        if(izraz[i]=='+' || izraz[i]=='-' || izraz[i]=='/' || izraz[i]=='*')
       {
           ch=izraz[i];

           op1 =e.pop()-'0';
            //System.out.print(op1+" ");

           op2 =e.pop()-'0';
    ArrayStack<String> e = new ArrayStack<String>(n);
    char ch=0;
    int op1,op2,result=0;
    for(int i=0; i<n; i++)
    {
       if(Character.isDigit(izraz[i]))
       {
         final StringBuilder number= new StringBuilder();

         while (izraz[i] != ' ') {
           number.append(izraz[i]);
           i++;    
         }

         e.push(number.toString());

          continue;
       }
        if(izraz[i]=='+' || izraz[i]=='-' || izraz[i]=='/' || izraz[i]=='*')
       {
           ch=izraz[i];

           op1 =Integer.parseInt(e.pop());
            //System.out.print(op1+" ");

           op2 =Integer.parseInt(e.pop());

I'd like to see one example where the conversion-type-id is looked up in the context of the entire postfix-expression

help you fix your problem In [basic.lookup.classref]/7 (C++14) we have (emphasis is mine): , Something like this:
struct C {
    operator int() { return 42; }
};

typedef int X;

int main() {
  C c;
  c.operator X();  // calls c.operator int();
}

SQL Server - date time conversion error - The conversion of a varchar data type to a datetime data type resulted in an o

around this issue That isn't the style 101, it's the style 100 (101 is MM/dd/yyyy). You also have a leading ' ' that you should to remove:
SELECT CONVERT(datetime,STUFF(' September 2, 2019 14:29:46',1,1,''),100);
