Objective: Solving problems using Nested If Structures or its variants 1. Write a C++ program to find the largest among three integer numbers using if-else statements. 2. Write a C++ program to find the smallest among three integer numbers using if-else statements. 3. Write a C++ program to find the smallest and largest numbers among five numbers using if-else statements. 4. Write a C++ program to implement a calculator with the following features: Exponentiation, Logarithm, Sine and Cosine input angle in degrees). Choose the code 'E' for exp, 'L' for log10, T for log base e, 'S' for sin, 'C' for cosine. s. Write a C++ program that accepts currency in Dirhams (AED) and converts it to any one of the six currencies using if-else statements. Available currency options should be: BAHRAIN DINAR KUWAIT DINAR QATAR RIYAL OMAN RIYAL SAUDI RIYAL CANADIAN DOLLAR (Choose the exchange rate from any available resources) Write a C++ program that accepts body temperature, taste status (0 for normal and I for loss of taste), smell status (o for normal and I for loss of smell), throat pain status (O for normal and 1 for throat pain) and generate the output messages as follows: "Immediate quarantine" (if the entries are: temp>37, taste=1, smell=1, throat pain=1) "PCR test required" (if the entries are: temp>37, taste =1, smell=1, throat pain=0) "DPI Test required" (if the entries are: temp>37, taste=0, smell=0, throat pain=0) "Normal and stay safe" (if 36
