assignment makes integer from pointer without a         


        

Answer 1

The problem is that a[4] is a char, whereas len1 is an array of chars!

When you declare

char a[7] = {...}

You're saying that you want a to be an array of chars and you're initializing the values at a to the values in {...}.

When you say a[4] you're saying go 4 along from where a is and use the value there, which is a char. But len1 is a char pointer so when you assign it to a[4] you get the warning!
