好的,下面是C语言的白盒测试程序流程图以及四种逻辑覆盖标准的测试用例:
程序流程图:
```

| 结束测试 |
+---------------------+
```
四种逻辑覆盖标准的测试用例示例:
1. 语句覆盖:
```c
#include <stdio.h>
int main() {
int a = 1;
int b = 2;
int c = a + b;
printf("c = %d\n", c);
return 0;
}
```
2. 判定覆盖:
```c
#include <stdio.h>
int main() {
int a = 1;
int b = 2;
if (a > b) {
printf("a > b\n");
} else {
printf("a <= b\n");
}
return 0;
}
```
3. 条件覆盖:
```c
#include <stdio.h>
int main() {
int a = 1;
int b = 2;
if (a > b) {
printf("a > b\n");
} else if (a == b) {
printf("a == b\n");
} else {
printf("a < b\n");
}
return 0;
}
```
4. 路径覆盖:
```c
#include <stdio.h>
int main() {
int a = 1;
int b = 2;
int c = 3;
if (a > b && a > c) {
printf("a is the largest\n");
} else if (b > a && b > c) {
printf("b is the largest\n");
} else {
printf("c is the largest\n");
}
return 0;
}
```
