From eb85069b669e754836b9d4587ba03d3af1a5e975 Mon Sep 17 00:00:00 2001 From: Tyge Løvset Date: Sun, 26 Mar 2023 00:27:45 +0100 Subject: development branch for 4.2 Removed uses of c_auto and c_with in documentation examples and code examples. Still using c_defer a few places. Renamed c11/fmt.h to c11/print.h. Some additions in ccommon.h, e.g. c_const_cast(T, x). Improved docs. --- misc/examples/csmap_insert.c | 134 +++++++++++++++++++++---------------------- 1 file changed, 66 insertions(+), 68 deletions(-) (limited to 'misc/examples/csmap_insert.c') diff --git a/misc/examples/csmap_insert.c b/misc/examples/csmap_insert.c index 64d71b12..3da245c7 100644 --- a/misc/examples/csmap_insert.c +++ b/misc/examples/csmap_insert.c @@ -1,13 +1,11 @@ -#include - // This implements the std::map insert c++ example at: // https://docs.microsoft.com/en-us/cpp/standard-library/map-class?view=msvc-160#example-19 - #define i_key int #define i_val int #define i_tag ii // Map of int => int #include +#include #define i_key int #define i_val_str #define i_tag istr // Map of int => cstr @@ -33,77 +31,77 @@ void print_istr(csmap_istr map) { int main() { // insert single values - c_auto (csmap_ii, m1) { - csmap_ii_insert(&m1, 1, 10); - csmap_ii_insert(&m1, 2, 20); - - puts("The original key and mapped values of m1 are:"); - print_ii(m1); - - // intentionally attempt a duplicate, single element - csmap_ii_result ret = csmap_ii_insert(&m1, 1, 111); - if (!ret.inserted) { - csmap_ii_value pr = *ret.ref; - puts("Insert failed, element with key value 1 already exists."); - printf(" The existing element is (%d, %d)\n", pr.first, pr.second); - } - else { - puts("The modified key and mapped values of m1 are:"); - print_ii(m1); - } - puts(""); - - csmap_ii_insert(&m1, 3, 30); + csmap_ii m1 = {0}; + csmap_ii_insert(&m1, 1, 10); + csmap_ii_push(&m1, (csmap_ii_value){2, 20}); + + puts("The original key and mapped values of m1 are:"); + print_ii(m1); + + // intentionally attempt a duplicate, single element + csmap_ii_result ret = csmap_ii_insert(&m1, 1, 111); + if (!ret.inserted) { + csmap_ii_value pr = *ret.ref; + puts("Insert failed, element with key value 1 already exists."); + printf(" The existing element is (%d, %d)\n", pr.first, pr.second); + } + else { puts("The modified key and mapped values of m1 are:"); print_ii(m1); - puts(""); } + puts(""); + + csmap_ii_insert(&m1, 3, 30); + puts("The modified key and mapped values of m1 are:"); + print_ii(m1); + puts(""); // The templatized version inserting a jumbled range - c_auto (csmap_ii, m2) - c_auto (cvec_ii, v) { - typedef cvec_ii_value ipair; - cvec_ii_push(&v, (ipair){43, 294}); - cvec_ii_push(&v, (ipair){41, 262}); - cvec_ii_push(&v, (ipair){45, 330}); - cvec_ii_push(&v, (ipair){42, 277}); - cvec_ii_push(&v, (ipair){44, 311}); - - puts("Inserting the following vector data into m2:"); - c_foreach (e, cvec_ii, v) - printf("(%d, %d) ", e.ref->first, e.ref->second); - puts(""); - - c_foreach (e, cvec_ii, v) - csmap_ii_insert_or_assign(&m2, e.ref->first, e.ref->second); - - puts("The modified key and mapped values of m2 are:"); - c_foreach (e, csmap_ii, m2) - printf("(%d, %d) ", e.ref->first, e.ref->second); - puts("\n"); - } + csmap_ii m2 = {0}; + cvec_ii v = {0}; + typedef cvec_ii_value ipair; + cvec_ii_push(&v, (ipair){43, 294}); + cvec_ii_push(&v, (ipair){41, 262}); + cvec_ii_push(&v, (ipair){45, 330}); + cvec_ii_push(&v, (ipair){42, 277}); + cvec_ii_push(&v, (ipair){44, 311}); + + puts("Inserting the following vector data into m2:"); + c_foreach (e, cvec_ii, v) + printf("(%d, %d) ", e.ref->first, e.ref->second); + puts(""); + + c_foreach (e, cvec_ii, v) + csmap_ii_insert_or_assign(&m2, e.ref->first, e.ref->second); + + puts("The modified key and mapped values of m2 are:"); + c_foreach (e, csmap_ii, m2) + printf("(%d, %d) ", e.ref->first, e.ref->second); + puts("\n"); // The templatized versions move-constructing elements - c_auto (csmap_istr, m3) { - csmap_istr_value ip1 = {475, cstr_lit("blue")}, ip2 = {510, cstr_lit("green")}; - - // single element - csmap_istr_insert(&m3, ip1.first, cstr_move(&ip1.second)); - puts("After the first move insertion, m3 contains:"); - print_istr(m3); - - // single element - csmap_istr_insert(&m3, ip2.first, cstr_move(&ip2.second)); - puts("After the second move insertion, m3 contains:"); - print_istr(m3); - puts(""); - } + csmap_istr m3 = {0}; + csmap_istr_value ip1 = {475, cstr_lit("blue")}, ip2 = {510, cstr_lit("green")}; + + // single element + csmap_istr_insert(&m3, ip1.first, cstr_move(&ip1.second)); + puts("After the first move insertion, m3 contains:"); + print_istr(m3); + + // single element + csmap_istr_insert(&m3, ip2.first, cstr_move(&ip2.second)); + puts("After the second move insertion, m3 contains:"); + print_istr(m3); + puts(""); - c_auto (csmap_ii, m4) { - // Insert the elements from an initializer_list - m4 = c_make(csmap_ii, {{4, 44}, {2, 22}, {3, 33}, {1, 11}, {5, 55}}); - puts("After initializer_list insertion, m4 contains:"); - print_ii(m4); - puts(""); - } + csmap_ii m4 = {0}; + // Insert the elements from an initializer_list + m4 = c_make(csmap_ii, {{4, 44}, {2, 22}, {3, 33}, {1, 11}, {5, 55}}); + puts("After initializer_list insertion, m4 contains:"); + print_ii(m4); + puts(""); + + cvec_ii_drop(&v); + csmap_istr_drop(&m3); + c_drop(csmap_ii, &m1, &m2, &m4); } -- cgit v1.2.3
