Help me in solving DSAAGP09 problem

My issue

What is run time error

My code

#include <stdio.h>

int main() {
    int arr1[100] = {2, 4, 6}; // First array
    int size1 = 3;

    int arr2[100] = {8, 10, 12, 14}; // Second array
    int size2 = 4;

   int merged[100]={2,4,6,8,10,12,14};
   int mergedSize=7;
   for(int i=0;i<mergedSize;i++){
       scanf("%d",merged[i]);
       
   }// Update the code below to solve the problem
    // Print the merged array
    for (int i = 0; i < mergedSize; i++) {
        printf("%d ", merged[i]);
    }

    return 0;
}
