Introduction Programmeringsteknik DT143G Lecture 7: Arrays (static) Pascal Rebreyend 26-11-2024 Pascal Rebreyend Programmeringsteknik DT143G  Introduction Today’s contents Static Arrays Loops, revisited homogenous data-structures Pascal Rebreyend Programmeringsteknik DT143G  Introduction variables and data Variables store: local and temporary information during computations data/information used as input or along the program Problem with variables: Store only one value Not suitable to handle big volume of data, sound, video,... ) Pascal Rebreyend Programmeringsteknik DT143G  Introduction data-structure data-structure: How we store data and have connections between the different data. An important field of programming Example: Arrays, matrices,... files have a structure too Later we will see other structures Pascal Rebreyend Programmeringsteknik DT143G  Introduction Arrays Array: 1-dimension structure All elements have the same type (float,integer,... ) In short, just a new datatype based on previous one we access directly each element (they are of the basic type). Each element has an index (0 for the first one) #include int main() { int a; a=4; printf("%d\n",a); return 0; } Pascal Rebreyend Programmeringsteknik DT143G  Introduction Arrays and loops Loops are naturally useful with arrays! #include int main() { int a,i; for (i=0;i
