Как отсортировать данный массив структур по полю name по возрастанию и вывести в консоль получившийся отсортированный массив структур?

Проверяй первый символ (с индексом ноль), // при равенстве со следущим
то есть

product p[10];

// ***

string tmp;
int z;
bool change;

for(int x = 0; x < 9; x++)
for(int y = x + 1; y < 10; y++)
{
z = 0;
change = false;
while(z < p[x].name.length() && z < p[y].name)
{
if(p[x].name[z] > p[y].name[z])
{
tmp = p[x].name;
p[x].name = p[y].name;
p[y].name = tmp;
change = true;
break;
}
z++;
}
if(!change)
{
if( p[x].name.length() > p[y].name.length() )
{
tmp = p[x].name;
p[x].name = p[y].name;
p[y].name = tmp;
}
}
}

Мага Магеррамов if (d->strategy != OnManualSubmit)
d->cache.empty();

если переменная стратеги не равна онмануалскрипт то
сбросить кеш
Мага Магеррамов или если -> это указатель то если указатель не на мануал скрипте то сбросить кеш
