print(int(var2) + var3)

# print(var2+var5) 
# now it is concatenating matlab error show kr dega bhai kyu kyuki maschine usko int ke form me nhi le rha. to usko int banao bhai.
# now  agla line kro run karega try kro 

print(int(var2) + int(var5)) # Type casting example. Ye run karega.




print(10 * "Hello World !!!\n")             # Iske through hello world 10 times print hoga
print(100 * (int(var5) + int(var2)))        # int(var5) + int(var2) iska value 14 aega ab usko bhi ham multiply kr sakte hai. ans is 1400
print(100 * str(int(var5) + int(var2)))     # add hone baad wo 14 bana jisko ham str() iska matlab ab maschine 14 ko 100 times likh dega
