Output: Marks for student one is: Maths:95 Physics:90 Chemistry:96 English:93 Computer:98 Traversing the Associative Array: Example:
Output: Looping using foreach: Student one got 95 in Maths Student one got 90 in Physics Student one got 96 in Chemistry Student one got 93 in English Student one got 98 in Computer Looping using for: Maths 95 Physics 90 Chemistry 96 English 93 Computer 98 Creating an associative array of mixed types
