Description

This metric measures the number of goto statements in a function.

break and continue statements are not counted.

The recommended upper limit on this metric is 0. For better readability of your code, avoid goto statements in your code. To detect use of goto statements, check for violations of MISRA C:2012 Rule 15.1.

To enforce limits on metrics, see Compute Code Complexity Metrics Using Polyspace.

#define SIZE 10
int initialize(int **arr, int loc);
void printString(int *);
void printErrorMessage(void);
void printExecutionMessage(void);


int main()
{
    int *arrayOfStrings[SIZE],len[SIZE],i;
    for ( i = 0; i < SIZE; i++ )
    {
        len[i] = initialize(arrayOfStrings,i);
    }

    for ( i = 0; i < SIZE; i++ )
    {
        if(len[i] == 0)
            goto emptyString;
        else
            goto nonEmptyString;
        loop: printExecutionMessage();
    }

emptyString:
    printErrorMessage();
    goto loop;
nonEmptyString:
    printString(arrayOfStrings[i]);
    goto loop;
}

In this example, the function main has 4 goto statements.
