C Programming - Cannot Call Function More Than Once


C Programming - Cannot Call Function More Than Once

With these it helps It does not "call the same first function". You change the value of your string inside the function, so after the first run of the function the string does not have spaces. Therefore the second and third call print the string unchanged:
code :
void display(char x[], char y){
    for(char i = 0; i < strlen(x); i++) {
        if(x[i] == ' ') {
           // this happens only upon first call! 
           x[i] = y;
       }
    }
    printf("%s\n", x);
}

it should still fix some issue
code :
int a=find(5,find(5,4));

find(5,4) returns 1

find(5,1) returns 4

I wish this helpful for you This is normal Python behaviour. Lists are passed by reference, so if you change the items in a list in a function, the changes will persist:
code :
def f(mylist):
    mylist[0] = 1

>>> l = [0, 0, 0]
>>> mylist(l)
>>> l
[1, 0, 0]

To fix this issue Functional programming is no different from procedural in that regard—you write definitions that you can reuse anywhere that they are in scope. You control what's in scope where with a variety of mechanisms, for example with module definitions, module export lists and module imports. So for example (in Haskell):
code :
module My.Module
  -- List of definitions exported from this module 
  ( doThing
  , alterData
  ) where

-- Any definitions exported from `My.Other.Module` will be in scope 
-- in this one
import My.Other.Module

-- Can't name this `data` because it's a reserved word in Haskell
yourData :: [String]
yourData = ["cat", "dog", "bird"]

doThing :: String -> String
doThing val = val ++ ", go away!" 

alterData :: [String] -> [String]
alterData strings = map doThings strings
Cannot call void user defined function inside main function in C programming

seems to work fine Your Program is unable to get the declaration of getString() method show just declare your method before calling it inside main(). What you can do is:
code :
#include<stdio.h>
/* demo.c:  My first C program on a Linux */
void getString()
{
printf("Hello World");
}

void main()
{
getString();
}

Does that help There is quite a lot wrong with your code: main() and getNum() are both declared as returning an int, yet main() never returns anything and getNum() returns only if the user enters 1. If you have a function returning anything other than void, make sure that every possible control flow has an appropriate return statement.
Then there is the issue with call by value vs call by reference. You should really look that up, because this is not the right place to explain and many people have written about better than I can.
