inna [77]

Answer:

The performance of the polymer is basically change by the various type of factors like shape, tensile strength and color.

The polymer based products are basically influenced by the environmental factors like light, acids or alkalis chemicals, salts and also heat.

The additives is one of the type of chemical polymer which basically include polymer matrix for improving the ability of processing of the polymer. It also helps to enhance the production and requirement of the polymer products in the environment.

int main()

{

//declare required variables

int SHour, SMin, MHour, MMin;

//check the hours are valid are not

while(SHour<0 || SHour>12)

{

cout<<"Invalid hours for standard time. "

<<"Try again..."<<endl;
