I usually get this error how to overcome this

#1

error- source.cpp: In function ‘bool solve(char*, int, int, int, int)’:
source.cpp:33:1: warning: control reaches end of non-void function [-Wreturn-type]

Take as input str, a string. The string is a mathematical expression e.g. “[a + {b + (c + d) + e} + f]”. Write a recursive function which tests if the brackets in expression are balanced or not and returns a Boolean value. Print the value returned.

Input Format
Enter the string

Constraints
None

Output Format
Display the boolean result

Sample Input
[a+{b+(c+d)+e}+f]
Sample Output
true

Hey @anubhavb11
add return statement in front of each recursive call

#3

why do we get this error like i am not able to understand why it will not give if i put return in every statement and what can i do for it?

#4

When we dont return something from a function which have a non-void return type then we get this error.
Even this will give the same error:

int solve(){
cout<<1;
}
int main() {
…
}

#5

actually i just figure out my logic is wrong for test case
)(())(-- it will return true what should i do?

#6

Have you done this problem using stacks ,if u have then try to do it in that way without using stack but by using recursion .
Recursion can be used to itterate the whole string and another array in argument can be treated as stack
