How can I insert another string in that array?

Thanks, simple, straight to the point, analytical.

One VERY important point when using strcpy() that really should have been mentionned: The destination string should be large enough to accept the source string. Otherwise, it will overflow on other memory adresses and potentially corrupt your program

You can also put space to occupy the string space being replaced if the string to replace another string is not large enough, not a permanent solution though: #include #include int main(){ char names[][10] = {"Hello", "Cameroon", "Doremi", "colagge"}; printf("No. of rows: %d ", sizeof(names)/sizeof(names[0] ) ) ; printf("No. of cols: %d ", sizeof(names)/sizeof(names[0] ) ) ; strcpy(names[1], "Dora " ); //Changes value of a string array. Put space to occupy the rest of the letters since the initial string is large. for(int i = 0; i < sizeof(names)/sizeof(names[0]) ; i++){ printf(" %s ", names[i]); } /* for(int i = 0; i < sizeof(names)/sizeof(names[0]); i++){ for(int j = 0; j < sizeof(names[0])/sizeof(names[0][0]); j++){ printf("%c", names[i][j]); } printf(" "); } */ return 0; }

For those who are dumb like me, the reason why he used two brackets for assigning an "array of strings" is because of *"an array of characters and the array of strings composed of those characters"* . A *string* in the _C language_ is simply *_a list of characters_* , but C prefers to associate it with the object known as an *array* , among other programming languages. So, having a list of words will usually entail creating a variable that stores two types of arrays, therefore it's important to use two brackets for what would then be a *2-dimensional array* . *_Definitions -_* *1. **_2-dimensional Array:_* [The incorporation of an array/list of elements that would intuitively involve the combination of two arrays.] *2. **_Arrays:_* [ 1.) A list of elements that can be manipulated in a coding project, assigned with *at least* a single bracket. 2.) A type of object in the C programming language.] *3. **_String:_* [A type of array that consists of characters.] *4. **_Characters:_* [ 1.) A data type in the C programming language, which represents a letter in the alphabet. 2.) A type of element that can be used in an array.] *5. **_Element:_* [A value that is stored in an array] *6. **_Bracket/Index Notation:_* [A notation that's used for indexing elements, but is used for limiting the number of possible elements within an array.]

Can we use use strings in 1d arrays?

@dkp8230 Жыл бұрын

I'm pretty late but i think no since a string itself is an array of characters so an array of strings must be a type of 2D array

A string is a 1D array of characters

yepp for example: #include #define MAX_LEN 10 int main(void) { char lecturer_name[MAX_LEN] = {'A','n','g','e','l','a' }; char lecturer_name[MAX_LEN] = "Angela"; //this is a string char word[MAX_LEN] = {'h', 'e', 'l', 'l', 'o', '\0'}; int i = 0; while (i < MAX_LEN) { printf("%c", lecturer_name[i]); i++; } printf(" "); return 0; }

I dont understand the math for the for loop... sizeof(cars) would be 2, since 0 counts as an index. sizeof(cars[0]) is Tesla, which is 5 characters... so wouldn't you be comparing 0, 1, and 2 against 2/5 which is 0.4? so shouldn't the loop break after the first element? so confused...
