What is the syntax of this code and also find what is the error in this code

Question

for(int i= ; i<=5; i++){
for(int a=1; a<=i; a++){

System.out.print("1");
}
System.out.println();
}

Answer 1

Error: Missing initializer for i in the first for loop. It should probably be for(int i=1;i<=5;i++).

Aa for the syntax, it's a nested for loop. For every value of i in the outer for loop, the inner loop is executed i times
