1.) Answer the following programs

a.) Let f be the following function:

int f(char *s, char *t)

{

char *p1, *p2;

for(p1 = s, p2 = t; *p1 != '\0'&& *p2 != '\0'; p1++, p2++){

if (*p1 == *p2) break;

}

return p1 -s;

}

What is the return value of f(“accd”, “dacd”)?

b.) What will be the output of the below program?

#include <stdio.h>

int main()

{

char x[]="ProgramDesign", y[]="ProgramDesign";

if(x==y){

printf("Strings are Equal");

}

Expert Solution

Question a:

Answer:2

Explanation :

Given function f() will check each character from two strings
when same character found then break the for loop
and return p1-s
hence it will return 2

Below screen shows the output

*******************************************

Question b:

Answer :Nothing will be printed

Explanation :

Character array x and y need to compare character by character by using strcmp(x,y)==0 will return 0 when strings are equal

Below screen shows the output

Below screen shows the output when strcmp() is used.

Translate the following function f to MIPS assembly code. int f(int a, int b, int c, int d) { return func(func(a,b), func(b+c,d)); } Assume the followings. • The prototype of function func is “int func(int a, int b);”. • You do not need to implement function func. The first instruction in function func is labeled “FUNC”. • In the implementation of function f, if you need to use registers $t0 through $t7, use the lower-numbered registers first. • In the...

1. Let g(s) = √ s. Find a simple function f so that f(g(s)) = 0. Hint: see Methods of computing square roots on Wikipedia. Use Newton’s method to estimate √ 2. Start with 3 different (and interesting) initial values of your choice and report the number of iterations it takes to obtain an accuracy of at least 4 digits. In python.

Consider the following function: int counter( int n) { int s = 0; for ( int i = 0; i < n; i++) for ( int j = i; j > 0; j--) s = s + 1; return s; } Part (a): How many times "s=s+1;" will be executed? Determine a precise count. Show all your work. Part (b): What is the time complexity of the "counter" function in terms of Big-O notation? Justify and show all your work.

a) Let S ⊂ R, assuming that f : S → R is a continuous function, if the image set {f(x); x ∈ S} is unbounded prove that S is unbounded. b) Let f : [0, 100] → R be a continuous function such that f(0) = f(2), f(98) = f(100) and the function g(x) := f(x+ 1)−f(x) is equal to zero in at most two points of the interval [0, 100]. Prove that (f(50) − f(49))(f(25) − f(24)) >...

[ Write in C, not C++] Define a function char* deleteSymbol(char *s, char x) that removes the character x from string s. For s[] = “America”, a call to deleteSymbol(s, ‘a’) converts s[] = “Ame”

Write in C programming language Write the function replace(char b[], char f[], char t[]). which finds the string 'f' in the string 'b' and replaces it with the string 't'. You can assume that f and t same length Example: char string[] = "zap"; replace(string, "ap", "oo"); --changes 'string' to "zoo". *don't assume substring being replaced is singular, or that its own substrings are unique. *Don't re scan letters already checked and replaced char string[] =...

Let (F, <) be an ordered field, let S be a nonempty subset of F, let c ∈ F, and for purposes of this problem let cS = {cx | x ∈ S}. (Do not use this notation outside this problem without defining what you mean by the notation.) Assume that c > 0. (i) Show that an element b ∈ F is an upper bound for S if and only if cb is an upper bound for cS. (ii)...

Let f(x, y) be a function such that f(0, 0) = 1, f(0, 1) = 2,...

Let f(x, y) be a function such that f(0, 0) = 1, f(0, 1) = 2, f(1, 0) = 3, f(1, 1) = 5, f(2, 0) = 5, f(2, 1) = 10. Determine the Lagrange interpolation F(x, y) that interpolates the above data. Use Lagrangian bi-variate interpolation to solve this and also show the working steps.
