Macmohan’s 1981
- This study followed women who booked home births in the UK in 1994 and matched them to similar women who booked hospital births.
- Outcomes were recorded for 5,971 home birth women and 4,724 matched hospital birth women. The groups were low-risk and well-matched.
- Planning a home birth was found to halve the chances of assisted or caesarean births compared to planning a hospital birth. Home births also had less reported high blood pressure and less stressful antenatal care.
- However, bias may exist since home birth women tended to be more educated/affluent and high-risk women who transferred care were excluded.

This document provides a summary of concepts related to demand elasticity, including:
1. Price elasticity of demand is measured as the percentage change in quantity demanded divided by the percentage change in price. It can be elastic (Ep>1), unit elastic (Ep=1), or inelastic (Ep<1).
2. Cross elasticity of demand measures the responsiveness of demand for one good to changes in price of another good. It can be positive for substitutes and negative for complements.
3. Income elasticity of demand measures the responsiveness of demand to changes in income. It can be elastic (Ey>1) for luxury goods or inelastic (

Bcsl 033 data and file structures lab s1-1
The program accepts the order and elements of two matrices as input from the user. It then multiplies the matrices and stores the product in a third matrix. The product matrix is then printed to the screen. The program checks that the matrices can be multiplied by verifying that the number of columns of the first matrix matches the number of rows of the second.

Qust & ans inc
The document contains explanations for the outputs of various C programming code snippets. Some key outputs summarized:
1. A program that checks if a float variable is less than a double constant outputs "C" because the float stores fewer bits of the double's binary value.
2. A program that uses pre-increment operators in a complex expression calculates the final value of a variable as 24.
3. Most programs output the values assigned or calculated by the expressions as written in C code, according to operator precedence rules and evaluation order.

introduction to c programming and C History.pptx
C programming was developed by Dennis Ritchie at Bell Labs in 1972. It was derived from an earlier language called BCPL. A C program typically includes source code, which is compiled into object code and linked to produce an executable file. The structure of a C program includes sections for documentation, definitions, global declarations, functions, and the main function.
Chapter 8 c solution
The document provides code snippets to copy the contents of one array into another array in reverse order using different approaches like loops, pointers, and functions. It also includes code to reverse an array without using additional memory by swapping elements, and to reverse an array using pointers.
2D array
A two dimensional array is an array that has two dimensions like rows and columns. The total number of elements in a two dimensional array is calculated by multiplying the number of rows and columns. A two dimensional array can be accessed using two indices like A[i][j] where i represents the row and j represents the column. Common operations on two dimensional arrays include storing and retrieving elements, finding the sum of boundary elements, finding the sum of diagonal elements, adding, subtracting and multiplying two dimensional arrays.
