c语言嵌套循环

---

---

一、c语言嵌套循环格式

---

for(初始值；表达式；表达式)
{for（初始值；表达式；表达式）{代码}
}

---

int main()
{for (int i = 0; i < 5; i++){for (int j = 0; j < 5; j++)printf("%d\t%d\n", i, j);}
}

---

二、嵌套循环案例九九惩罚口诀

---

int main()
{for (int i = 1; i < 10; i++){for (int j = 1; j <= i; j++){printf("%d*%d=%d", i, j, i * j);}printf("\n");}
}
