What is RAM memory? and What is ROM?Who designed one is
temparary and another is permanent?why they designed like
that?By using far pointer which type data(whether
hexadecimal)we can access?
An interactive c program to read basic salary of 15
persons. each person gets 25% of basic as HRA, 15%of basic
as conveyance allowances, 10%of basic as entertainment
allowances.The total salary is calculated by adding
basic+HRA+CA+EA.Calculate how many out of 15 get salary
above 10,000.Rs also print the salary of each employee
What will be result of the following program?
void myalloc(char *x, int n)
{
x= (char *)malloc(n*sizeof(char));
memset(x,\0,n*sizeof(char));
}
main()
{
char *g="String";
myalloc(g,20);
strcpy(g,"Oldstring");
printf("The string is %s",g);
}
a) The string is : String
b) Run time error/Core dump
c) The string is : Oldstring
d) Syntax error during compilation
e) None of these
