How to assign a return value from function to a variable

I am trying to assign the return value of int leftPyramid(void); to a variable left so I can use printf to print the pattern.

#include <stdio.h>
#include <cs50.h>

int leftPyramid(void);

int main(void){
    int left;

The following is the code for int leftPyramid(void); it creates the following pattern:

   #
  ##
 ###
####

int leftPyramid(void);{
    for (int i = 1; i<=num_rows; i++){
        for(int j=1; j<=num_rows-i; j++){
            printf(" ");
            }
        for(int k= 1; k<=i; k++){
            printf("#");
            }
        printf("\n");
        }
  
}

The following line is causing the error but I can't figure why.

left = int leftPyramid(void); //this line seems to be the problem.


int num_rows = get_int("height: \n");
printf("%d", left);

This is the prototype of your function:

int leftPyramid(void);

in order to call it you need

left = leftPyramid();

When you fixed that you will notice the problem mentioned by Carcigenicate in the comment, i.e. you will have to return something meangingful from your function. Sadly I have no idea what that could be, but it is not part of your question.
