What is Array ...

 #include <stdio.h>


int main()

{ int marks [] ={10,20,30,40,50,60,70,80,90,};

    printf("%d\n", marks[6]);


    return 0;

}


2D Array....👇

#include <stdio.h>


int main()

{ //int marks1[]= {97,98,83,95,90};

 //int marks2[]= {92,97,92,95,76};

 //int marks3[]= {80,82,83,90,60};

 

 int marks[3][5] = {

      { 97,98,83,95,90},

     {92,97,92,95,76},

     {80,82,83,90,60}

     

 };

    printf("%d", marks[2] [3]);


    return 0;

}
