ANALYSIS EXPERIMENT: DETERMINATION OF ASCORBIC ACID IN VITAMIN C TABLETS THEORY: Ascorbic acid‚ C6H8O6‚ MM = 176.13‚ can be oxidized to form dehydroascorbic acid by bromine via the following reaction: The bromine or iodine used in the titration is generated by adding an excess amount of KBr or KI to an acidified solution of the sample according to the following reaction: BrO3- + 5 Br- + 6 H+ 3 Br2 + 3 H2O IO3- + 5 I- + 6 H+ 3 I2 + 3 H2O Sodium thiosulfate solutions

BASIC INPUT/OUTPUT The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming. C++ I/O occurs in streams‚ which are sequences of bytes. If bytes flows from a device like a keyboard‚ a disk drive‚ or a network connection etc. to main memory‚ this is called input operation and if bytes flows from main memory to a device like a display screen

However‚ we never considered the permanence of a variable or its scope i.e. the portion of the program where the variable is valid or recognized. All these factors are considered with storage classes. In C‚ variables differ in behavior from those in most of the other languages. A variable in C can have anyone of the four storage classes: 1. Automatic Storage class 2. External Storage class 3. Static Storage class 4. Register Storage class There are many ways in which a storage class
