Accumulate values in a range.

Accumulates the values in the range [first,last) using operator+(). The initial value is init. The values are processed in order.

Parameters

__first	Start of range.
__last	End of range.
__init	Starting value to add other values to.

Returns

The final sum.

Accumulate values in a range with operation.

Accumulates the values in the range [first,last) using the function object __binary_op. The initial value is __init. The values are processed in order.

Parameters

__first	Start of range.
__last	End of range.
__init	Starting value to add other values to.
__binary_op	Function object to accumulate with.

Returns

The final sum.

Compute inner product of two ranges.

Starting with an initial value of __init, multiplies successive elements from the two ranges and adds each product into the accumulated value using operator+(). The values in the ranges are processed in order.

Parameters

__first1	Start of range 1.
__last1	End of range 1.
__first2	Start of range 2.
__init	Starting value to add other values to.

Returns

The final inner product.

Compute inner product of two ranges.

Starting with an initial value of __init, applies __binary_op2 to successive elements from the two ranges and accumulates each result into the accumulated value using __binary_op1. The values in the ranges are processed in order.

Parameters

__first1	Start of range 1.
__last1	End of range 1.
__first2	Start of range 2.
__init	Starting value to add other values to.
__binary_op1	Function object to accumulate with.
__binary_op2	Function object to apply to pairs of input values.

Returns

The final inner product.

Return list of partial sums

Accumulates the values in the range [first,last) using the + operator. As each successive input value is added into the total, that partial sum is written to __result. Therefore, the first value in __result is the first value of the input, the second value in __result is the sum of the first and second input values, and so on.

Parameters

__first	Start of input range.
__last	End of input range.
__result	Output sum.

Returns

Iterator pointing just beyond the values written to __result.

Return list of partial sums

Accumulates the values in the range [first,last) using __binary_op. As each successive input value is added into the total, that partial sum is written to __result. Therefore, the first value in __result is the first value of the input, the second value in __result is the sum of the first and second input values, and so on.

Parameters

__first	Start of input range.
__last	End of input range.
__result	Output sum.
__binary_op	Function object.

Returns

Iterator pointing just beyond the values written to __result.

Return differences between adjacent values.

Computes the difference between adjacent values in the range [first,last) using operator-() and writes the result to __result.

Parameters

__first	Start of input range.
__last	End of input range.
__result	Output sums.

Returns

Iterator pointing just beyond the values written to result.

Return differences between adjacent values.

Computes the difference between adjacent values in the range [__first,__last) using the function object __binary_op and writes the result to __result.

Parameters

__first	Start of input range.
__last	End of input range.
__result	Output sum.
__binary_op	Function object.

Returns

Iterator pointing just beyond the values written to result.
