A `while` loop in C repeatedly executes a block of code **as long as a given condition is true**. Here's a simple example to help you:

#define CATCH_CONFIG_MAIN
#include <catch2/catch.hpp>

int _testmain();


int powerCounter(int a, int b);

TEST_CASE("Counter returns 3 for a=2, b=3", "[powerCounter]") {
    int ret = powerCounter(2, 3);
    REQUIRE(ret == 3);
}

TEST_CASE("Counter returns 0 for a=5, b=0", "[powerCounter]") {
    int ret = powerCounter(5, 0);
    REQUIRE(ret == 0);
}

TEST_CASE("Counter returns 2 for a=7, b=2", "[powerCounter]") {
    int ret = powerCounter(7, 2);
    REQUIRE(ret == 2);
}

TEST_CASE("Counter returns 1 for a=10, b=1", "[powerCounter]") {
    int ret = powerCounter(10, 1);
    REQUIRE(ret == 1);
}

TEST_CASE("Counter returns 4 for a=3, b=4", "[powerCounter]") {
    int ret = powerCounter(3, 4);
    REQUIRE(ret == 4);
}
