Chapter 2, Problem 41RQ

Explanation of Solution

Modes of operation:

The three modes of operation which can be selected by the key switch of a processor are as follows:

  • RUN position mode
  • PROG position mode
  • REM position mode

RUN position mode:

  • To execute ladder program and activate output devices, the processor is made in RUN mode.
  • When a processor is in RUN mode, it disables online program editing and also prevents to change the processor mode using programmer interface device.

PROG position mode:

  • Here, the term PROG refers to program.
  • When the processor is in PROG mode, it secures the processor from scanning or executing the ladder program...

Which statement regarding SGA_MAX_SIZE is true? SGA_MAX_SIZE is modifiable after an instance is started, only when Automatic Memory Management is used. SGA_MAX_SIZE is not dyamically modifiable. SGA_MAX_SIZE is ignored when MEMORY_TARGET > 0. SGA-MAX_SIZE must be specified when SGA_TARGET > 0
Explian this C program  #include <stdio.h> unsigned int rotateRight(unsigned int num, unsigned int bits) { unsignedint bit_count =sizeof(unsignedint) *8; bits = bits % bit_count; // Handle cases where bits >= bit_count return (num >> bits) | (num << (bit_count - bits)); } int main() { unsignedint num, bits; printf("Enter a number: "); scanf("%u", &num); printf("Enter the number of bits to shift: "); scanf("%u", &bits); printf("After rotation: %u\n", rotateRight(num, bits)); return0; }
Explian thiS C program #include<stdio.h> int countSetBits(int n) {    int count = 0;    while (n) {        count += n & 1;        n >>= 1;    }    return count;} int main() {    int num;    printf("Enter a number: ");    scanf("%d", &num);    printf("Output: %d units\n", countSetBits(num));    return 0;}
